1
00:00:02,250 --> 00:00:03,150
Welcome back, my friends.

2
00:00:03,170 --> 00:00:06,180
I hope you enjoy the last class, so what are we going to do here?

3
00:00:06,870 --> 00:00:11,820
I'm going to create additional function for calculating all of the patients.

4
00:00:12,030 --> 00:00:14,790
So method for calculating.

5
00:00:17,030 --> 00:00:17,810
The patients.

6
00:00:19,820 --> 00:00:24,740
So we're going to put it inside the clinic, OK, what because this matter will be mostly used by the

7
00:00:24,740 --> 00:00:28,520
clinic and it will not have any connection with the other things.

8
00:00:28,670 --> 00:00:30,590
So I'm going to say Colque patients here.

9
00:00:33,320 --> 00:00:37,860
This might slightly differ from what I have in the final version, but that's pretty much it.

10
00:00:38,360 --> 00:00:42,590
So I'm going to say patience and I'm going to put a data here.

11
00:00:43,790 --> 00:00:44,210
Right.

12
00:00:47,480 --> 00:00:53,390
Or I'm just going to say, Ereira here, I don't want to confuse you here, are we going to pass past

13
00:00:53,390 --> 00:00:56,030
the area of patients?

14
00:00:56,180 --> 00:01:04,010
But before that, I'm just going to let here be patients that will be equal to work, equal to zero.

15
00:01:04,430 --> 00:01:04,780
Good.

16
00:01:05,180 --> 00:01:10,820
So I declare E and I initialized a variable to zero.

17
00:01:11,120 --> 00:01:16,280
Now I'm just going to look through for each and I'm going to say element

18
00:01:19,280 --> 00:01:22,250
so you can say element current, whatever it's there.

19
00:01:22,490 --> 00:01:28,940
And let's create here the patients that we create the variable before.

20
00:01:29,090 --> 00:01:32,360
So I want the store to loop through each and every element.

21
00:01:35,330 --> 00:01:43,370
And I want the store to grab the positions while I'm doing this, you will see very soon, so I'm just

22
00:01:43,370 --> 00:01:46,590
going to come out of the area.

23
00:01:46,880 --> 00:01:54,230
OK, so this function will not work at the moment because first we need to go to the CLIDE reports and

24
00:01:54,230 --> 00:01:55,130
we need to call it.

25
00:01:55,280 --> 00:02:02,020
So first, as I told you, I need to create an area of, um, an area of patients.

26
00:02:02,180 --> 00:02:03,220
So how are we going to do this?

27
00:02:03,830 --> 00:02:10,140
Let's create first let so I'm not going to create I'm going to create an instance of the class.

28
00:02:10,200 --> 00:02:13,580
So clinic that will be new clinic.

29
00:02:14,220 --> 00:02:14,570
Good.

30
00:02:15,380 --> 00:02:22,010
So this is this I'm going to use it for calling the functions so const patients.

31
00:02:23,720 --> 00:02:25,610
This will be equal to clinics.

32
00:02:26,180 --> 00:02:32,780
I'm using these clinics here, the area that I had before and I'm going to put the I'm going to on top

33
00:02:32,780 --> 00:02:34,520
of that, I'm going to create a map mechanism.

34
00:02:34,520 --> 00:02:37,580
This map method will return unary and put it here.

35
00:02:37,760 --> 00:02:40,640
So in the map method, they have the access of the current element.

36
00:02:40,640 --> 00:02:40,960
Right.

37
00:02:41,320 --> 00:02:46,680
And I'm going to do it with every function and I'm going to say, OK, return for the current.

38
00:02:46,700 --> 00:02:54,410
So it's going to look through these clinics and I want to return these patients daily patients right

39
00:02:55,280 --> 00:02:55,550
now.

40
00:02:55,550 --> 00:03:05,390
If I do a lot of patients, I would like to see an array with one hundred five, one hundred seventy

41
00:03:05,390 --> 00:03:08,150
two, thirty three and sixty six.

42
00:03:09,330 --> 00:03:11,060
Now this is in my final one.

43
00:03:11,300 --> 00:03:13,250
So if I don't want to put in every.

44
00:03:15,510 --> 00:03:22,410
Like that, it will give me one big area of this so even I can use this now, I'm just going to show

45
00:03:22,410 --> 00:03:23,290
you the two things.

46
00:03:23,850 --> 00:03:27,690
So if I have it inside of sorry, inside of an every.

47
00:03:29,940 --> 00:03:38,340
So when I call now, I can use the clinic, this instance here of the clinic last night called the Issues

48
00:03:38,520 --> 00:03:46,510
and I'm going to get past this patient's every right, because now we know that we have unary here.

49
00:03:47,010 --> 00:03:47,400
Good.

50
00:03:49,210 --> 00:03:50,410
Area of an area.

51
00:03:50,450 --> 00:03:57,490
Now this is coming from inside that one inch here.

52
00:03:58,870 --> 00:03:59,240
Right.

53
00:03:59,530 --> 00:04:10,170
So before I do this, I'm just going to tell you, if I can, a the element why you use zero position.

54
00:04:10,300 --> 00:04:11,950
You will see very shortly.

55
00:04:12,220 --> 00:04:16,620
So I control the entire area here and it was working.

56
00:04:16,630 --> 00:04:18,290
That's why I just put it there for testing.

57
00:04:18,530 --> 00:04:23,470
Now, I don't need this one anymore, but now let's just print out the one element.

58
00:04:23,470 --> 00:04:25,110
It will give me the area.

59
00:04:25,360 --> 00:04:41,770
So if I try now to get through this and if I cassella the patients, that will happen, it will give

60
00:04:41,770 --> 00:04:49,150
me some crazy things, because this is not how we managed to get the values of the value values actually

61
00:04:49,150 --> 00:04:50,870
in the zero position.

62
00:04:50,890 --> 00:04:53,140
That's why I just put it zero like this.

63
00:04:53,420 --> 00:04:58,510
OK, now if you don't want to use it like this now, the patient actually will work.

64
00:04:58,990 --> 00:05:00,220
It will calculate everything.

65
00:05:00,430 --> 00:05:03,730
But if you don't want to use it like this, this is in my final version.

66
00:05:04,210 --> 00:05:06,370
OK, so I'm going to create it like this.

67
00:05:07,450 --> 00:05:10,600
And so let's create it like this one.

68
00:05:10,600 --> 00:05:15,430
It's like in the final and I'm going to show you what you need to change in order to be a little bit

69
00:05:15,430 --> 00:05:17,130
more easy without this zero.

70
00:05:17,140 --> 00:05:17,440
Right.

71
00:05:17,650 --> 00:05:22,560
OK, so a lot I don't need here to control a lot of the patient, actually.

72
00:05:22,810 --> 00:05:27,760
Now you know that I'm going to look through each and every element grab these values is stored in the

73
00:05:27,760 --> 00:05:28,170
patient.

74
00:05:28,180 --> 00:05:29,390
That was the logic here.

75
00:05:29,860 --> 00:05:32,890
OK, now I just want to consult a couple of things.

76
00:05:33,580 --> 00:05:38,170
And if you don't want to waste time, that folder.

77
00:05:38,170 --> 00:05:45,470
Sorry, remember that file that we put here on the where was it and why.

78
00:05:45,470 --> 00:05:46,630
It's not what didn't open.

79
00:05:49,960 --> 00:05:51,050
How strange is this?

80
00:05:51,540 --> 00:05:54,340
OK, let's read it

81
00:05:57,430 --> 00:05:58,810
actually to have that file here.

82
00:05:58,840 --> 00:05:59,320
Here is.

83
00:06:02,460 --> 00:06:03,200
OK.

84
00:06:05,120 --> 00:06:06,020
That is strange.

85
00:06:06,110 --> 00:06:07,560
Never happened before, right?

86
00:06:08,120 --> 00:06:08,640
Just going to.

87
00:06:09,590 --> 00:06:15,860
So, I mean, a starter folder, I'm going to open file, so it should be opening the file.

88
00:06:15,890 --> 00:06:16,400
Here it is.

89
00:06:16,970 --> 00:06:19,620
But this is from the desktop, maybe because it was open.

90
00:06:19,910 --> 00:06:23,860
Now, just going to copy this one, copy the entire console lot from here.

91
00:06:24,830 --> 00:06:27,680
It just going to close this one for now.

92
00:06:27,950 --> 00:06:33,730
And I'm going back to the starter, so I don't have anything in the starter right now.

93
00:06:33,830 --> 00:06:39,680
I'm going to be it here I don't want to do to write and waste time of you guys so deep Asian.

94
00:06:39,920 --> 00:06:46,300
What I'm doing slash already got length and this will get the length of the actually the length of the

95
00:06:46,310 --> 00:06:50,930
error is four, because what we do have, we have four clinics.

96
00:06:51,110 --> 00:06:51,440
Good.

97
00:06:51,590 --> 00:06:54,630
If we, if you have, if you add one more it will be five.

98
00:06:54,950 --> 00:07:02,770
Now the patients total and after that what I'm doing, the patients times 50 to get the income and to

99
00:07:02,780 --> 00:07:03,800
get the average income.

100
00:07:03,800 --> 00:07:04,820
I'm using this.

101
00:07:06,290 --> 00:07:06,990
I'm 50.

102
00:07:07,080 --> 00:07:13,940
OK, so what I haven't shown you before was that in the template literals, you can use the simple map

103
00:07:14,570 --> 00:07:17,000
and this is called interpolation.

104
00:07:17,120 --> 00:07:21,380
So you can use the simple math functions inside here and that will not affect.

105
00:07:21,650 --> 00:07:27,470
Oh OK, let's save it and let's see if that is the reality here.

106
00:07:27,670 --> 00:07:28,210
Here it is.

107
00:07:28,370 --> 00:07:29,570
One, two, three and four.

108
00:07:29,900 --> 00:07:32,030
And I'm getting this nice.

109
00:07:34,590 --> 00:07:39,950
So I'm just going to come along, I'm going to remove this, and now everything should be normal.

110
00:07:40,170 --> 00:07:40,480
Good.

111
00:07:40,560 --> 00:07:42,630
We have one, two, three, four, all done.

112
00:07:42,930 --> 00:07:46,150
So that is the old way.

113
00:07:46,230 --> 00:07:56,340
I mean, the original I'm going to see here, original as it is in the final file.

114
00:07:56,710 --> 00:07:58,760
OK, I'm going to create something else.

115
00:07:59,160 --> 00:08:00,920
I'm going to say corporations.

116
00:08:00,930 --> 00:08:04,490
I'm going to use the same one and I'm going to get modified.

117
00:08:06,510 --> 00:08:10,800
Now, this will do as Jacklin is this.

118
00:08:10,800 --> 00:08:12,060
But I'm going to change here.

119
00:08:13,140 --> 00:08:15,390
I'm just going to pass in the element.

120
00:08:16,170 --> 00:08:18,030
But here I need to fix some things.

121
00:08:19,200 --> 00:08:24,930
Remember, here we just storing everything in the patients as an array of areas.

122
00:08:25,050 --> 00:08:30,270
But what we can do is actually modify.

123
00:08:32,730 --> 00:08:34,710
Let me just copy this to.

124
00:08:37,330 --> 00:08:45,440
And some say a modified version, and it will be exactly the same thing.

125
00:08:46,690 --> 00:08:50,410
So I'm just going to comment this one right in here.

126
00:08:50,410 --> 00:08:55,660
I'm going to pass and not as an area, just one on one big area.

127
00:08:56,380 --> 00:09:02,460
And what that will do, it will give me not applicable.

128
00:09:02,470 --> 00:09:02,920
Let's see.

129
00:09:02,920 --> 00:09:04,270
Why is this happening?

130
00:09:04,690 --> 00:09:07,830
OK, let's go back first.

131
00:09:07,960 --> 00:09:09,120
I'm going to cancel that, OK?

132
00:09:09,130 --> 00:09:09,400
Yeah.

133
00:09:09,850 --> 00:09:12,300
Because I don't I don't access the same function.

134
00:09:12,310 --> 00:09:15,430
And I'm going to say here, what was the name Modify.

135
00:09:15,560 --> 00:09:15,910
Right.

136
00:09:16,090 --> 00:09:19,000
Because I'm trying to do X is the same function as before.

137
00:09:19,180 --> 00:09:20,260
Maybe you got this one.

138
00:09:20,380 --> 00:09:21,820
If you did Bravo

139
00:09:24,310 --> 00:09:32,950
and now you work here is the same thing, but it's easier you don't think of each element of the position

140
00:09:32,950 --> 00:09:33,640
you need to grab.

141
00:09:33,820 --> 00:09:35,440
Now, this is easier.

142
00:09:40,440 --> 00:09:44,790
So I'm going to leave the modified version, so you're going to have this one is going to be different

143
00:09:44,790 --> 00:09:47,670
from the final, but this will be in the final.

144
00:09:47,760 --> 00:09:51,110
You know, you have different different starter.

145
00:09:51,360 --> 00:09:54,480
And when you when we finish this one, it will be a little bit different.

146
00:09:54,510 --> 00:09:56,480
OK, now, what else we need to do here?

147
00:09:57,300 --> 00:09:58,670
Go back to the report.

148
00:09:59,820 --> 00:10:02,190
We need to do five, six, seven and eight.

149
00:10:02,190 --> 00:10:08,430
That's a newly opened a dental clinic, two thousand sixty two thousand twenty, the smallest and the

150
00:10:08,430 --> 00:10:09,680
largest number of patients.

151
00:10:10,440 --> 00:10:11,490
How are we going to do this?

152
00:10:11,880 --> 00:10:14,370
OK, let's think a little bit.

153
00:10:16,590 --> 00:10:26,040
First right here, clinic sighs You know what else we need here to do, we need to grab the newly opened

154
00:10:26,040 --> 00:10:29,600
a dental clinic and we're going to use this structuring for this.

155
00:10:30,060 --> 00:10:39,960
But first, let's create a constant called year details, and I'm going to store all the years for each

156
00:10:39,960 --> 00:10:40,720
and every clinic.

157
00:10:40,740 --> 00:10:41,700
So how are we going to do this?

158
00:10:41,820 --> 00:10:42,960
I'm going to access the clinics.

159
00:10:42,960 --> 00:10:44,910
I'm going to use the same same here

160
00:10:47,850 --> 00:10:48,390
map.

161
00:10:49,350 --> 00:10:51,420
And I'm going to say current.

162
00:10:54,120 --> 00:10:57,240
And I want Kuranda to access the year of Bill.

163
00:10:58,080 --> 00:11:02,390
So look what I'm doing, I'm doing I'm seeing as a patients, I'm storing this here.

164
00:11:02,400 --> 00:11:05,370
So if I do cause a lot of years of build.

165
00:11:08,610 --> 00:11:15,860
Here are details I will have a list of years in one area, not as a separate area, just in one area,

166
00:11:16,310 --> 00:11:18,630
as I did here with the patients.

167
00:11:18,830 --> 00:11:19,140
Good.

168
00:11:20,010 --> 00:11:26,990
Now, what I need to do is actually I need to use this area here, the newly created from the map function,

169
00:11:28,220 --> 00:11:38,030
and I need to create a function, get min max and I need to pass in this year details.

170
00:11:38,250 --> 00:11:40,490
So actually it becomes a lot.

171
00:11:43,510 --> 00:11:46,490
This entire function, but look what is happening here.

172
00:11:46,750 --> 00:11:54,400
I don't actually call with the clinic, so my idea is to use this function outside, I'm not going to

173
00:11:54,400 --> 00:11:56,120
create it inside the clinic.

174
00:11:56,440 --> 00:12:03,910
And the reason why, because the same function can be reused even for the plaques, which I'm not going

175
00:12:03,910 --> 00:12:04,180
to do.

176
00:12:04,180 --> 00:12:05,340
But that will be your homework.

177
00:12:05,620 --> 00:12:06,060
Right.

178
00:12:06,910 --> 00:12:08,250
But you will see.

179
00:12:08,800 --> 00:12:13,330
So here I'm seeing function Bemax.

180
00:12:13,720 --> 00:12:14,100
Right.

181
00:12:14,110 --> 00:12:19,000
And what we need for this function is to pass the data cool.

182
00:12:19,750 --> 00:12:20,250
In here.

183
00:12:20,260 --> 00:12:21,790
We're going to use the spread operator.

184
00:12:25,920 --> 00:12:28,220
So if you're confused, how are we going to use the spread of freedom?

185
00:12:28,420 --> 00:12:30,690
It's going to be really simple.

186
00:12:30,690 --> 00:12:31,850
Let me just write it down.

187
00:12:32,160 --> 00:12:36,230
So math doesn't mean you're going to use this mean method here.

188
00:12:36,240 --> 00:12:47,180
I'm going to use the spread operator and cost Max left that Max, and I'm going to say three that data.

189
00:12:47,850 --> 00:12:53,400
OK, I'm going to return an error rate of me and comma Max.

190
00:12:54,390 --> 00:12:56,000
So let me explain what this is doing.

191
00:12:56,190 --> 00:13:03,210
So the spread operator, I do have how many years I do have to actually it's giving me the result back.

192
00:13:03,480 --> 00:13:05,130
I had four years here.

193
00:13:05,760 --> 00:13:11,940
And what this will do, it will create a four different variables in this neat map that mean method

194
00:13:11,940 --> 00:13:13,290
that I haven't shown you before.

195
00:13:13,440 --> 00:13:18,630
It will go through all of these variables, all of these data, and it will find the minimum value is

196
00:13:18,630 --> 00:13:19,950
store it in this constant.

197
00:13:20,280 --> 00:13:21,600
Same goes for Max.

198
00:13:21,810 --> 00:13:27,270
It will go through four of the variables, find the biggest one is stored in the max.

199
00:13:27,420 --> 00:13:29,740
And I'm just returning it now.

200
00:13:29,740 --> 00:13:33,270
How I told you that we're going to do this now.

201
00:13:33,270 --> 00:13:35,370
I'm going we are going to use the structure.

202
00:13:35,650 --> 00:13:37,430
So why the structure?

203
00:13:37,530 --> 00:13:40,350
Because it's going to be easy to see here.

204
00:13:46,460 --> 00:13:46,830
Right.

205
00:13:47,120 --> 00:13:52,910
So I'm going to create a constant here with two values in the first, I'm going to see new built

206
00:13:55,430 --> 00:13:57,970
and all built, right.

207
00:13:58,280 --> 00:14:05,480
So you can create any variable you want, but put it all built in after that.

208
00:14:07,220 --> 00:14:12,050
I'm going to grab the result from this function so I don't need this console anymore.

209
00:14:12,290 --> 00:14:14,050
So how was this structuring was working?

210
00:14:14,300 --> 00:14:22,430
So here these two variables are going to grab the result from these two and actually for this function

211
00:14:22,430 --> 00:14:27,980
and this function will return to Herry values.

212
00:14:27,980 --> 00:14:28,300
Right.

213
00:14:28,430 --> 00:14:32,750
So that every so the destructing was working with areas, with objects.

214
00:14:32,900 --> 00:14:34,490
So that's why I use it here.

215
00:14:34,900 --> 00:14:36,910
And you can use the structure.

216
00:14:36,950 --> 00:14:40,580
Now, what we need to do is to see Conjola.

217
00:14:43,040 --> 00:14:52,550
So we're going to use number five and we see the newly open dental.

218
00:14:55,010 --> 00:15:08,810
Come on, dental clinic was opened in the year, and I'm going to access new build like that and I'm

219
00:15:08,810 --> 00:15:14,870
going to copy this one and I'm going to put it one more and I'm going to see six.

220
00:15:15,380 --> 00:15:18,380
And here should not be the newly opened.

221
00:15:18,430 --> 00:15:30,470
It will be the oldest, the oldest dental clinic or the newest dental clinic that's open.

222
00:15:30,620 --> 00:15:32,750
The oldest in the league was open in a year.

223
00:15:32,750 --> 00:15:35,780
And we need to change this or build hope.

224
00:15:35,780 --> 00:15:40,130
This is going to work and it's 20, 20 in 2016.

225
00:15:40,140 --> 00:15:44,000
So how we grab these values, we're grabbing from here to 2016.

226
00:15:44,000 --> 00:15:44,620
Two thousand.

227
00:15:44,630 --> 00:15:47,840
OK, let's put here let's change this.

228
00:15:47,840 --> 00:15:48,410
Twenty twenty.

229
00:15:48,620 --> 00:15:50,450
Make it twenty two thousand.

230
00:15:52,190 --> 00:15:52,640
Right.

231
00:15:52,640 --> 00:15:58,670
So the maximum will be the newest will be twenty nineteen and this one will be right.

232
00:16:00,740 --> 00:16:01,330
Where was it.

233
00:16:03,110 --> 00:16:04,420
Here is number five and six.

234
00:16:05,180 --> 00:16:10,570
So the newest was open it in two thousand and the oldest was open it in two thousand ninety.

235
00:16:10,610 --> 00:16:11,060
Cool.

236
00:16:11,930 --> 00:16:15,600
I'm just going to change it back to twenty twenty five.

237
00:16:15,710 --> 00:16:17,180
You can put any years you want there.

238
00:16:17,390 --> 00:16:21,710
Now one more thing is that we can we use the same function.

239
00:16:21,710 --> 00:16:22,640
I'm just going to copy it

240
00:16:25,610 --> 00:16:28,310
and I'm going to put it here and I'm going to say min

241
00:16:30,800 --> 00:16:34,400
max and plus I need to grab this.

242
00:16:34,560 --> 00:16:36,920
So even here you should go there.

243
00:16:37,820 --> 00:16:43,190
Now, tips for finding the smallest number of patients.

244
00:16:43,670 --> 00:16:46,730
We need to grab the patients.

245
00:16:46,730 --> 00:16:47,030
Right.

246
00:16:47,210 --> 00:16:53,510
So instead of this current that you're built, I'm going to see daily patients and I'm going to change

247
00:16:53,510 --> 00:16:55,910
here to clinic patients.

248
00:16:59,910 --> 00:17:07,110
Nice going to pass the same one so I can reuse the function, I'm going to grab the main max and I'm

249
00:17:07,110 --> 00:17:18,930
just going to change here the mean Max and here she be, the smallest number number of patients in one

250
00:17:19,560 --> 00:17:27,960
day was, OK, I'm just going to copy and this is actually not five and six is seven.

251
00:17:28,080 --> 00:17:28,580
Sorry.

252
00:17:28,590 --> 00:17:29,010
And eight.

253
00:17:31,400 --> 00:17:42,770
And this should be the opposite, the largest no good and here is the smallest is thirty three and the

254
00:17:42,770 --> 00:17:44,180
largest is one seventy two.

255
00:17:44,330 --> 00:17:46,880
How this is working, we use the same function.

256
00:17:47,270 --> 00:17:50,840
OK, go back here.

257
00:17:51,410 --> 00:17:55,340
One, two, five one seventy two, thirty three and sixty six.

258
00:17:55,430 --> 00:18:00,980
So this is the smallest number of patient Docklands and the largest is having the Brighton Coupe.

259
00:18:01,160 --> 00:18:02,900
So we are finished.

260
00:18:02,900 --> 00:18:08,030
Actually this is identical to what we have in our report a little bit, maybe change of the wording,

261
00:18:08,390 --> 00:18:10,730
but that is pretty much it.

262
00:18:11,060 --> 00:18:12,500
We are done now.

263
00:18:12,500 --> 00:18:15,500
We need to do the parking report and that's it.

264
00:18:15,500 --> 00:18:17,130
We will do that in the next lecture.

265
00:18:17,130 --> 00:18:18,170
I hope you enjoyed this one.

266
00:18:18,530 --> 00:18:27,530
And I will be not angry because we got a little bit from we cheat a little bit copy from the final final

267
00:18:27,800 --> 00:18:30,440
at the gas file because I want to speed up things.

268
00:18:30,800 --> 00:18:32,450
And yes, that's pretty much it.

269
00:18:32,450 --> 00:18:33,500
I don't want to waste your time.

270
00:18:33,650 --> 00:18:34,760
So see you in the next one.
