1
00:00:01,830 --> 00:00:02,550
Welcome back, my friend.

2
00:00:02,580 --> 00:00:05,400
Welcome to our walkthrough.

3
00:00:05,490 --> 00:00:11,120
I'm going to walk through the final version of this project so you don't have to do this.

4
00:00:11,130 --> 00:00:14,010
You don't have to listen to this lecture if you're planning to work with me.

5
00:00:14,280 --> 00:00:16,060
And that will start from the next lecture.

6
00:00:16,380 --> 00:00:21,750
So if you don't plan to do to work with me, if you just want to know what the discourse I mean, what

7
00:00:21,750 --> 00:00:27,480
this section is about, what we're going to do about this challenge, then I'm going to show you and

8
00:00:27,480 --> 00:00:31,200
I'm going to explain you the final version of these six challenge.

9
00:00:31,380 --> 00:00:34,860
So here I do have this clinic working.

10
00:00:34,860 --> 00:00:37,280
You do have this report that I've shown you last night.

11
00:00:37,680 --> 00:00:39,610
So you have the final and you have the story.

12
00:00:39,900 --> 00:00:42,090
So I'm just going to open the Vasco here.

13
00:00:42,960 --> 00:00:43,830
I'm going to navigate.

14
00:00:45,860 --> 00:00:53,000
Just going to open the folder and I'm going to go to the final one, right, and in the final, you're

15
00:00:53,000 --> 00:00:58,430
going to have index, you're going to have this image here, this image, I just grab it from Splash.

16
00:00:58,430 --> 00:01:00,280
And that's why I'm saying thank you here.

17
00:01:00,710 --> 00:01:11,690
And this is the finished version of our product of our application, and that is for this application

18
00:01:11,690 --> 00:01:15,670
will be actually for practicing six skills.

19
00:01:15,680 --> 00:01:16,040
Right.

20
00:01:16,350 --> 00:01:20,150
OK, so let's start from DOT and I'm going to open.

21
00:01:23,780 --> 00:01:31,940
I'm going to open this index open with the server and it's going to open up here, but I don't want

22
00:01:31,940 --> 00:01:33,190
to use this Firefox.

23
00:01:33,210 --> 00:01:34,190
I'm just going to close this.

24
00:01:34,650 --> 00:01:43,700
I'm going to go to Google Google Chrome, open this bastard down here, and that's pretty much it.

25
00:01:43,730 --> 00:01:47,510
Now, one thing here, my entire styling is this.

26
00:01:47,510 --> 00:01:53,040
So I didn't worry too much because this is just for practicing this challenge, you see to get you better.

27
00:01:53,060 --> 00:01:53,410
Right.

28
00:01:53,700 --> 00:01:55,460
OK, I'm done with this.

29
00:01:57,230 --> 00:02:04,040
So the first thing's first in our report, seeing that all of our clinics are parking, have a building

30
00:02:04,040 --> 00:02:10,670
address in your built in, that is a perfect, perfect scenario for creating our corporate parent or

31
00:02:11,080 --> 00:02:11,830
superclass.

32
00:02:12,170 --> 00:02:15,360
So I'm going to name the superclass building it.

33
00:02:15,440 --> 00:02:20,770
After that, I'm going to extend it to the parking into the clinic class that I have.

34
00:02:20,780 --> 00:02:28,280
So this every class, every class needs to have a constructor in the address and your building goes

35
00:02:28,280 --> 00:02:28,620
here.

36
00:02:28,880 --> 00:02:33,250
Now we initialize them through the parameters we're passing here.

37
00:02:33,860 --> 00:02:36,090
Now, this is our parent or super class.

38
00:02:36,560 --> 00:02:41,510
Now let's create a parking class, know let's create a completely class, because that is pretty much

39
00:02:41,510 --> 00:02:44,830
we are talking about clinic report in parking report.

40
00:02:44,900 --> 00:02:46,670
Maybe you were thinking how many classes I need.

41
00:02:46,910 --> 00:02:47,330
Wow.

42
00:02:47,810 --> 00:02:48,380
It's simple.

43
00:02:48,380 --> 00:02:52,220
You need to do some classes in one super class.

44
00:02:52,580 --> 00:02:56,240
OK, now the solution is not a final solution.

45
00:02:56,240 --> 00:03:00,310
You can create a better solution if you spend more time if you think more.

46
00:03:00,770 --> 00:03:01,050
Right.

47
00:03:01,310 --> 00:03:02,780
OK, this is just for practicing.

48
00:03:03,050 --> 00:03:11,210
Debarking will have its constructor its own variables, except these two with its own parameters so

49
00:03:11,540 --> 00:03:16,190
we can tackle the superclass in order to create that inheritance with this building.

50
00:03:16,550 --> 00:03:16,850
Right.

51
00:03:17,150 --> 00:03:19,090
So here you say this, that size.

52
00:03:19,280 --> 00:03:26,900
Now, this is the size of a parking, including this is the size of the parking, including hourly in

53
00:03:26,900 --> 00:03:27,860
all the parking.

54
00:03:27,860 --> 00:03:28,190
Right.

55
00:03:28,820 --> 00:03:30,230
That including should be.

56
00:03:30,230 --> 00:03:30,500
Right.

57
00:03:30,860 --> 00:03:37,040
So now, if the size I'm not going to use it in this project, but I put it there and I'm going to tell

58
00:03:37,040 --> 00:03:37,510
you why.

59
00:03:37,850 --> 00:03:42,860
So I have four spot spots, hourly spots, prize hourly in full day price.

60
00:03:43,160 --> 00:03:43,490
Right.

61
00:03:43,500 --> 00:03:47,360
We do have two spots we don't want mention there here.

62
00:03:47,570 --> 00:03:53,840
But I just see average number of patients, every average number of all day parking that is full for

63
00:03:53,840 --> 00:03:57,980
spots or all spots you can put in hourly spot spots.

64
00:03:57,980 --> 00:04:06,800
And also they do have a separate pricing here, three dollars per hour and nine dollars for all day

65
00:04:06,800 --> 00:04:10,400
parking, cuz that's why I do have this.

66
00:04:10,400 --> 00:04:12,020
That's why I had it in the constructor.

67
00:04:12,350 --> 00:04:12,790
Nice.

68
00:04:12,800 --> 00:04:19,640
So the clinic, the clinic will have daily patient in this size, which I put it is the fault here.

69
00:04:20,030 --> 00:04:23,450
This default will be used later in this method here.

70
00:04:23,450 --> 00:04:28,580
But don't worry, at the beginning when you called it, if you got it together with me, we will leave

71
00:04:28,580 --> 00:04:33,500
this size without the full value, some extending to the super class of the parent.

72
00:04:34,670 --> 00:04:37,520
Right in initializing these two here.

73
00:04:37,950 --> 00:04:40,370
OK, now don't worry about the methods.

74
00:04:40,370 --> 00:04:45,050
Now inside, I'm going to create now the data.

75
00:04:45,560 --> 00:04:47,990
This will be the data for clinics.

76
00:04:48,260 --> 00:04:50,690
This will be the data for the parking's right.

77
00:04:50,780 --> 00:04:59,390
So the data for the clinics, I will create a nursery full of new clinics so this scene can be achieved

78
00:04:59,570 --> 00:05:03,470
if we create like this concept first clinic

79
00:05:06,350 --> 00:05:07,400
equal to new.

80
00:05:07,430 --> 00:05:08,870
And I can copy the rest of it.

81
00:05:09,140 --> 00:05:13,100
Now, this is still OK.

82
00:05:13,100 --> 00:05:15,190
So I'm creating a nuisance of a clinic class.

83
00:05:15,740 --> 00:05:20,270
But for the second I will need to put second here.

84
00:05:20,360 --> 00:05:20,720
Right.

85
00:05:21,650 --> 00:05:25,880
And that's not obviously my solution.

86
00:05:25,880 --> 00:05:27,020
It's not looking good.

87
00:05:27,200 --> 00:05:30,100
So that's why I put it inside of an area.

88
00:05:30,320 --> 00:05:31,900
Same goes for the parking space.

89
00:05:31,910 --> 00:05:39,800
Now, this is why here my data, you can just change it.

90
00:05:40,130 --> 00:05:47,240
Now, here for the clinic, we have the address, the Yarraville, and we have the total number of patients,

91
00:05:47,240 --> 00:05:51,290
daily patients in these three is the actual size.

92
00:05:51,290 --> 00:05:54,380
So I have three the second one, three again, then one.

93
00:05:54,380 --> 00:06:03,410
Then to remember that we talk about that, the new data structure that allows you to create your own

94
00:06:04,190 --> 00:06:05,360
data inside.

95
00:06:05,360 --> 00:06:08,570
For example, you can have a string's you get as a key.

96
00:06:08,570 --> 00:06:13,850
I'm saying as a key, you can have a different data type and you can have a stream, you can have a

97
00:06:15,200 --> 00:06:15,770
numbers.

98
00:06:15,890 --> 00:06:17,480
You can have a boolean values.

99
00:06:17,750 --> 00:06:19,070
That's why I use the street.

100
00:06:19,440 --> 00:06:22,100
OK, now same goes for bar.

101
00:06:22,480 --> 00:06:27,010
Then after that, I create to function called clinical report, they will be empty at the beginning

102
00:06:27,340 --> 00:06:30,280
and the parking report there will be empty at the beginning.

103
00:06:30,610 --> 00:06:37,360
And I'm calling this function some passing data into those two functions, these two data here.

104
00:06:37,900 --> 00:06:41,770
If I'm calling colleagues with different name, the same here.

105
00:06:41,920 --> 00:06:49,120
So if he comes out of this clinic, it will contain this boy here if you call, because a lot of the

106
00:06:49,130 --> 00:06:51,880
markings, it will contain this part of you.

107
00:06:52,060 --> 00:06:57,010
OK, now you know how this is going to do is going to work.

108
00:06:57,730 --> 00:07:01,210
So I'm going straight to work to clinics.

109
00:07:02,920 --> 00:07:06,870
So create an instance of a new of the clinic glass like this.

110
00:07:06,880 --> 00:07:10,290
I'm going to use it later that I'm using constant patient.

111
00:07:10,660 --> 00:07:14,050
But this clinic is actually the data from here.

112
00:07:14,290 --> 00:07:18,670
So I'm going to use the map method to loop through all of them through the current element.

113
00:07:19,090 --> 00:07:25,690
And I'm just going to store it in a variable daily patients and that will give me this one hundred five

114
00:07:26,290 --> 00:07:28,150
hundred seventy two that will create.

115
00:07:30,040 --> 00:07:32,370
So if I do it like this, I'm going to show it to you.

116
00:07:32,680 --> 00:07:36,340
Now, if it comes a lot of patients

117
00:07:39,100 --> 00:07:43,210
now, I will have the number of all of the patients and you will see.

118
00:07:47,470 --> 00:07:54,210
Here is area four 105 one seven two three three six six, as I told you, they're coming from this one

119
00:07:54,210 --> 00:07:57,250
on five one seven to thirty three and six six.

120
00:07:57,430 --> 00:07:57,750
Cool.

121
00:07:57,880 --> 00:08:00,430
So what I'm going to do with this patient, so I do have them.

122
00:08:00,730 --> 00:08:06,580
This map method helped me to store it as an area and put it here because remember Map Method will always

123
00:08:06,580 --> 00:08:08,440
create a new every night.

124
00:08:08,710 --> 00:08:13,770
So clinic that called patient and I'm passing this part here.

125
00:08:14,200 --> 00:08:14,550
Good.

126
00:08:14,770 --> 00:08:17,080
This is the clinic from here.

127
00:08:17,500 --> 00:08:20,680
The instance it's not clinics don't get confused.

128
00:08:21,220 --> 00:08:21,580
Right.

129
00:08:21,820 --> 00:08:23,740
So passing this patients.

130
00:08:24,040 --> 00:08:26,260
So let's find where it is called patient is.

131
00:08:26,380 --> 00:08:35,960
So what you think because I'm calling it from the class clinic should be inside the class here is called

132
00:08:36,100 --> 00:08:36,550
patient.

133
00:08:36,730 --> 00:08:38,350
It's inside this class here.

134
00:08:38,530 --> 00:08:38,890
Right.

135
00:08:39,310 --> 00:08:41,410
So this class will take the data.

136
00:08:42,370 --> 00:08:47,440
I will create a very will collect the patients and that will be equal to zero.

137
00:08:47,860 --> 00:08:53,140
And I'm going to loop through each and every element here and why I use the element zero.

138
00:08:53,260 --> 00:09:00,760
OK, I'm just going comes along the entire element and you will see why.

139
00:09:04,880 --> 00:09:13,400
We're just going to refresh here, and I do have a area one only one element, and on the zero position,

140
00:09:13,670 --> 00:09:14,820
he's 105.

141
00:09:15,200 --> 00:09:17,480
So how do we grab that position?

142
00:09:17,570 --> 00:09:22,190
Well, simply, if you put in the element of zero, it will just grab the numbers.

143
00:09:24,720 --> 00:09:34,140
Here is right, so I can sum up all of the patients, so this is how we do that now, the connections

144
00:09:34,140 --> 00:09:38,150
block everything, how we find the average.

145
00:09:38,340 --> 00:09:43,040
So the average is what I have here after looping through all of this.

146
00:09:43,230 --> 00:09:49,920
So it will have like a 500 Rizzotto three hundred and something in then I'm going to divide by the Aeris

147
00:09:50,220 --> 00:09:51,850
length that I've passed in.

148
00:09:52,140 --> 00:09:53,640
So that's the length is zero.

149
00:09:53,670 --> 00:09:55,300
One, two, three, four.

150
00:09:55,440 --> 00:09:58,910
So I'm going to divide it by four and that will give me the average.

151
00:09:59,310 --> 00:10:09,240
Now the all of the patients is just here and income is if I multiply the number of patients by 50 and

152
00:10:09,240 --> 00:10:13,980
if I want an average income, I just grab this and put it down.

153
00:10:13,990 --> 00:10:14,500
Swiftie.

154
00:10:14,550 --> 00:10:21,870
Now, before when we use the template literals, I never show you that we can do a simple math operations

155
00:10:21,870 --> 00:10:22,150
here.

156
00:10:22,290 --> 00:10:28,740
Now you know how to do it, and that's why the result will bring me these four here.

157
00:10:30,660 --> 00:10:31,130
Cool.

158
00:10:31,620 --> 00:10:32,940
Now let's move on.

159
00:10:32,950 --> 00:10:34,230
I'm just going to get rid of this.

160
00:10:36,760 --> 00:10:38,050
In my I don't have it.

161
00:10:40,560 --> 00:10:43,870
OK, now I don't have it anymore, cool, just wait.

162
00:10:44,160 --> 00:10:48,120
I need to get this one because I'm going to have multiple errors now.

163
00:10:48,120 --> 00:10:50,100
I need to go five, six, seven and eight.

164
00:10:50,520 --> 00:10:50,880
Good.

165
00:10:51,030 --> 00:10:57,300
Now I need to go back to the clinic report and see what I'm doing for five, six, seven and eight.

166
00:10:57,660 --> 00:11:05,760
OK, I'm going to use the structure here, but first I'm going to use this map again and I'm going to

167
00:11:05,760 --> 00:11:11,160
go through all of these current elements and I'm just going to grab the euro build.

168
00:11:11,430 --> 00:11:14,970
Then I'm going to put here inside the constant years details.

169
00:11:15,120 --> 00:11:16,200
So if I cause a lot.

170
00:11:19,090 --> 00:11:27,400
Your details, I would expect to have two thousand, so this is one three with four values, so I get

171
00:11:27,400 --> 00:11:29,750
the index from zero until three, right.

172
00:11:29,910 --> 00:11:36,230
And these are coming from twenty six thousand nineteen twenty twenty two thousand sixty.

173
00:11:36,420 --> 00:11:37,650
Okey dokey.

174
00:11:38,410 --> 00:11:41,370
Now, there you have it.

175
00:11:41,590 --> 00:11:45,300
I'm feeling these three back to the get mean Max.

176
00:11:45,520 --> 00:11:48,480
So where I do this function, I'm not calling it with clinic.

177
00:11:49,290 --> 00:11:51,250
So what was my point then?

178
00:11:51,250 --> 00:11:55,510
I can we use this function later for the parks.

179
00:11:55,510 --> 00:11:55,970
But I'm not.

180
00:11:55,970 --> 00:11:56,290
I'm not.

181
00:11:56,620 --> 00:11:57,700
That will be your homework.

182
00:11:58,030 --> 00:12:10,630
And so that get me Max is actually function outside is outside both the cleaning and parking.

183
00:12:10,810 --> 00:12:11,140
Right.

184
00:12:11,260 --> 00:12:12,190
It's outside.

185
00:12:12,520 --> 00:12:15,780
So I can even put it inside, but I want to use it like this.

186
00:12:16,030 --> 00:12:23,920
So now that data or actually the area that I have here, I'm going to use the sprint operator, this

187
00:12:23,920 --> 00:12:31,120
map that mean it will actually, for example, I had four years here and it will spread it into four

188
00:12:31,120 --> 00:12:31,810
variables.

189
00:12:31,930 --> 00:12:38,410
And this means that that map don't mean it will go through that for variables and it will extract the

190
00:12:38,410 --> 00:12:41,470
minimum value and it will store it here back.

191
00:12:41,620 --> 00:12:42,760
The same goes for Max.

192
00:12:43,240 --> 00:12:49,990
The screen operator will spread those four years into four different variables and it will find the

193
00:12:49,990 --> 00:12:53,310
max that the value of those because they were numbers, right?

194
00:12:53,840 --> 00:12:59,010
Actually, it doesn't matter because they were numbers and it can store it back.

195
00:12:59,380 --> 00:13:05,580
So I'm returning an array of two these two values and that is good for the district tree.

196
00:13:06,090 --> 00:13:08,290
I remember how we use the destruction.

197
00:13:08,710 --> 00:13:15,490
Everything that we put on the left, we put two variables in the result from this is going to be attached

198
00:13:15,490 --> 00:13:16,360
to this variable.

199
00:13:16,510 --> 00:13:19,090
So that's why we can just print it out now.

200
00:13:19,180 --> 00:13:20,230
We can do the same thing.

201
00:13:21,610 --> 00:13:27,600
You can do the same thing for the smallest in the greatest number of patients.

202
00:13:27,790 --> 00:13:29,770
So I'm using the same function again.

203
00:13:30,310 --> 00:13:40,480
But instead of storing the years I'm putting here the clinic patients, I mean, I put this value here

204
00:13:41,080 --> 00:13:43,590
one oh five one seven two thirty three.

205
00:13:43,840 --> 00:13:48,880
So here the maximum will be one seven two and the median value will be three.

206
00:13:49,120 --> 00:13:49,960
Let's have a look.

207
00:13:51,250 --> 00:13:52,930
Here is the smallest number of patients.

208
00:13:52,930 --> 00:13:56,260
Thirty three and the largest one seven to cut.

209
00:13:56,860 --> 00:14:05,230
Now the last four is connected with that size variable that I've told you that we just put it to equal

210
00:14:05,230 --> 00:14:05,860
to two.

211
00:14:06,250 --> 00:14:11,920
For example, I'm doing clinics, all the data that I have on top.

212
00:14:12,190 --> 00:14:12,530
Right.

213
00:14:13,150 --> 00:14:16,540
And I'm doing a for each end with the error function.

214
00:14:16,900 --> 00:14:21,070
I am accessing the current element, this building classification.

215
00:14:21,120 --> 00:14:27,250
OK, so according to my belief, this was the best place to use maps.

216
00:14:28,720 --> 00:14:32,920
So we create a concept called clinic size and that will be equal to new empty map.

217
00:14:33,070 --> 00:14:36,730
And after that we set the map and we did one, two and three.

218
00:14:37,570 --> 00:14:40,600
So the one to set was two here.

219
00:14:41,020 --> 00:14:44,260
So if we don't specify a value.

220
00:14:47,450 --> 00:14:51,590
Where was here so three, three, one, two.

221
00:14:51,620 --> 00:14:59,450
So if we don't specify any value here in our data, then the default will kick in and it will immediately

222
00:14:59,450 --> 00:15:00,830
be two.

223
00:15:01,130 --> 00:15:02,210
That will be normal.

224
00:15:02,400 --> 00:15:02,720
Right.

225
00:15:02,990 --> 00:15:08,360
And I'm concerned about this address because I have the access to the super from the superclass.

226
00:15:08,360 --> 00:15:10,250
Right, was built in.

227
00:15:10,490 --> 00:15:14,180
Also, I have the access to the year in clinic site.

228
00:15:14,570 --> 00:15:19,780
I'm getting this that size actually the size here.

229
00:15:20,090 --> 00:15:26,300
So this size, it will not always be too, because I also have three three.

230
00:15:26,480 --> 00:15:27,510
One, two.

231
00:15:27,560 --> 00:15:28,400
OK, save it.

232
00:15:28,400 --> 00:15:34,010
Now go back here and it will say big clinic, big, small, normal.

233
00:15:34,490 --> 00:15:40,030
But look what happens if I don't specify the value here.

234
00:15:40,190 --> 00:15:43,220
That's why we learned about the fault parameters.

235
00:15:43,380 --> 00:15:47,150
So if I save it back, they all of them will be normal clinic.

236
00:15:47,150 --> 00:15:47,480
Right.

237
00:15:47,780 --> 00:15:48,620
Because this.

238
00:15:51,470 --> 00:15:53,630
The full parental will start kick in.

239
00:15:54,000 --> 00:16:01,660
Right, that's it, just going to go back, make it like this, we are done with the clinical reports.

240
00:16:01,780 --> 00:16:03,960
Now, let's do with a parking report.

241
00:16:04,250 --> 00:16:06,290
This has a little bit more calculation.

242
00:16:06,920 --> 00:16:10,970
And I add, as I told you, I didn't expect to do everything here.

243
00:16:10,970 --> 00:16:17,170
But, yeah, I just that's why we recorded the first lecture, because I need to put all of this here.

244
00:16:17,660 --> 00:16:21,130
OK, now I'm going to do with these Parkin's data.

245
00:16:21,140 --> 00:16:27,290
I'm going to map in I'm going to X into the current element with the Arrow function and I'm going to

246
00:16:27,290 --> 00:16:35,900
create an array with one, two, three, four, four different their values in there now stored in these

247
00:16:36,500 --> 00:16:37,250
parking data.

248
00:16:37,280 --> 00:16:45,380
So if I do plug working data, cool, here it is.

249
00:16:45,380 --> 00:16:53,450
I do have four areas and inside I have nineteen sixty three and these three is price it per hour and

250
00:16:53,450 --> 00:16:55,210
this nine is full day price.

251
00:16:55,340 --> 00:17:03,170
This 90 is actual full spot in these 60 is the hourly spot and the same goes for this, same goes for

252
00:17:03,170 --> 00:17:04,400
this, the same goes for this.

253
00:17:04,730 --> 00:17:07,730
You now have four arrays.

254
00:17:10,100 --> 00:17:16,460
So what I'm doing this, I'm creating this call function again outside the parking, we can just put

255
00:17:16,460 --> 00:17:19,230
it inside a parking because we never going to use it anywhere else.

256
00:17:19,910 --> 00:17:20,420
Here it is.

257
00:17:20,570 --> 00:17:28,400
So now your homework will be to put this function, if you want, inside parked here, because you can

258
00:17:28,400 --> 00:17:31,810
because this function will never be used by anybody else.

259
00:17:31,910 --> 00:17:34,380
But I just want to use it outside, OK?

260
00:17:34,820 --> 00:17:36,440
Now, where was it called?

261
00:17:36,470 --> 00:17:36,970
Here it is.

262
00:17:37,340 --> 00:17:40,990
I create a couple of variables in these variables.

263
00:17:41,000 --> 00:17:44,630
I initially initially declare and initialize in the same line.

264
00:17:44,780 --> 00:17:46,880
I think we haven't done this before now.

265
00:17:46,880 --> 00:17:47,740
It's a good idea.

266
00:17:48,530 --> 00:17:54,270
So I'm looking through all of the data and I'm storing for everything here.

267
00:17:54,530 --> 00:18:00,370
Now, this multiplication element of zero, I'm just going to tell you why I'm using element of zero.

268
00:18:00,980 --> 00:18:06,200
So if it comes a lot element now, you will see what will happen.

269
00:18:10,400 --> 00:18:12,920
Actually, I need to get rid of that one, so.

270
00:18:15,910 --> 00:18:26,920
And yet no element of zero, this is 90, this is about full parking, element of one will be 60.

271
00:18:27,160 --> 00:18:28,550
It's about hourly parking.

272
00:18:28,570 --> 00:18:29,660
That's why I can access it.

273
00:18:29,890 --> 00:18:31,860
That's why you need to store this here.

274
00:18:32,140 --> 00:18:40,360
The income is element of zero this year, 90 multiplied by nine in the nine is the element number three.

275
00:18:41,080 --> 00:18:41,440
Right.

276
00:18:41,830 --> 00:18:44,110
That's why I did the same goes for number one.

277
00:18:44,110 --> 00:18:47,980
And number two, I just want to multiply 60 times three.

278
00:18:48,370 --> 00:18:54,820
And after that I'm returning all this in.

279
00:18:55,210 --> 00:19:04,600
When I return this area, I can again use it, this restructuring method.

280
00:19:04,840 --> 00:19:12,790
But the restructuring will help me everything that I grab from this part to put it inside these variables.

281
00:19:12,910 --> 00:19:18,450
And I'm just pointing out that all of them, that's pretty much it.

282
00:19:19,000 --> 00:19:26,800
Now, the last part is we need to find which of the parking's have click.

283
00:19:27,520 --> 00:19:36,280
Should be parking here, has more than one hundred hourly or all the spots.

284
00:19:36,430 --> 00:19:40,660
Now, I'm just using just going to lot of this one.

285
00:19:40,660 --> 00:19:41,790
I'm just going to get rid of it.

286
00:19:43,240 --> 00:19:43,720
Good.

287
00:19:46,240 --> 00:19:46,600
Yeah.

288
00:19:46,630 --> 00:19:48,400
I don't have anything else let you see.

289
00:19:51,970 --> 00:19:54,450
By I will get rid of that as well.

290
00:19:54,920 --> 00:19:59,990
I think just put it here, we don't need this one anymore.

291
00:20:00,000 --> 00:20:01,300
I just wanted to make it clean.

292
00:20:01,700 --> 00:20:02,010
Good.

293
00:20:02,210 --> 00:20:03,950
Now, now where we are.

294
00:20:03,950 --> 00:20:04,520
Here it is.

295
00:20:04,520 --> 00:20:06,530
We are in this seven and eight.

296
00:20:07,040 --> 00:20:10,760
So finding which.

297
00:20:13,220 --> 00:20:20,690
Parking has more than one hundred hourly or all day spots.

298
00:20:20,810 --> 00:20:23,780
OK, so I'm going to use for the first time finding index.

299
00:20:24,200 --> 00:20:26,690
So indexer, that is going to be the constant.

300
00:20:27,050 --> 00:20:33,610
And I'm going to look through it again with a map method and I'm going to grab all of these four spots.

301
00:20:34,040 --> 00:20:38,450
So that will create an array of indexes.

302
00:20:38,750 --> 00:20:44,150
And I'm going to say find the index where the element is greater or equal to 100.

303
00:20:44,330 --> 00:20:52,280
Right now, when I know this index, I can especially grab the parking index, for example, if it's

304
00:20:52,340 --> 00:20:57,140
going to be zero and that has more or equal to a hundred.

305
00:20:57,140 --> 00:20:59,910
All the parking spots in the same goes for here.

306
00:21:00,200 --> 00:21:04,190
Now, I'm just going to tell you how it's going to work.

307
00:21:04,220 --> 00:21:05,300
OK, here it is.

308
00:21:07,490 --> 00:21:16,040
So we actually look for this value and this value, so ninety one hundred eighty one seventy six actually.

309
00:21:16,040 --> 00:21:16,330
Right.

310
00:21:16,730 --> 00:21:20,410
So which is the heart, which is the greatest number here.

311
00:21:20,690 --> 00:21:23,720
That will be the right street.

312
00:21:24,170 --> 00:21:24,560
Right.

313
00:21:24,710 --> 00:21:28,080
Because I'm just going to happy brightness.

314
00:21:28,080 --> 00:21:31,430
Speed for nine has more than an equal to 100.

315
00:21:31,430 --> 00:21:32,720
All the parking spots.

316
00:21:33,140 --> 00:21:33,360
Good.

317
00:21:33,770 --> 00:21:36,150
And the same goes for this value here.

318
00:21:36,350 --> 00:21:40,710
So this one looks a little bit off, right.

319
00:21:40,730 --> 00:21:45,190
Because I'm just going to save it like this in order to show you.

320
00:21:45,740 --> 00:21:47,290
So I'm looking for this.

321
00:21:47,300 --> 00:21:48,170
Don't worry about this.

322
00:21:48,170 --> 00:21:50,020
One hundred and fifty because it's something else.

323
00:21:50,510 --> 00:21:54,080
It's of the size now, which is the greatest year.

324
00:21:54,080 --> 00:21:57,260
Nineteen hundred eighty seven to six hundred.

325
00:21:57,920 --> 00:22:01,150
So that's why these Bridon Street is going to be picked up.

326
00:22:01,880 --> 00:22:02,260
Cool.

327
00:22:02,810 --> 00:22:05,350
The same goes for the hourly.

328
00:22:05,690 --> 00:22:07,790
Which one has a hundred or more.

329
00:22:08,000 --> 00:22:08,900
This one Dockland.

330
00:22:08,900 --> 00:22:10,400
So that's why it's going here.

331
00:22:11,780 --> 00:22:12,130
Good.

332
00:22:12,200 --> 00:22:15,290
Now if you don't understand some of the next three join me.

333
00:22:15,570 --> 00:22:17,660
You know we will do step by step.

334
00:22:17,660 --> 00:22:22,010
But if you're happy with the way I explain it to you, you don't have to.

335
00:22:22,220 --> 00:22:24,770
You're just going to graph.

336
00:22:25,130 --> 00:22:28,430
You can just grab the final one, tweak some things.

337
00:22:28,760 --> 00:22:31,300
If you have something in mind to change it.

338
00:22:31,490 --> 00:22:33,590
That's the out and practice.

339
00:22:33,800 --> 00:22:34,920
That is pretty much it.

340
00:22:35,210 --> 00:22:37,340
So I hope you enjoyed this.

341
00:22:38,180 --> 00:22:45,470
And this is something that I do because I want to save your time if you don't want to listen to me doing

342
00:22:45,470 --> 00:22:46,580
all the codings.

343
00:22:46,580 --> 00:22:46,870
Right.

344
00:22:47,090 --> 00:22:47,780
Thank you very much.

345
00:22:48,170 --> 00:22:54,080
But I hope that I'm going to see you in the next lecture where I explain how are we going to start with

346
00:22:54,080 --> 00:22:54,230
this?

347
00:22:54,590 --> 00:22:55,040
That's it.

348
00:22:55,070 --> 00:22:56,270
See you in the next one.
