1
00:00:01,030 --> 00:00:05,030
In the last video he spoke about why the any type is a very bad thing to have inside of application

2
00:00:05,600 --> 00:00:11,720
right now coordinates is of type any and it's only the case because Jason got returns a value of type

3
00:00:11,720 --> 00:00:12,100
any.

4
00:00:12,200 --> 00:00:17,280
And that's because typescript just can't predict what Jason does pass is going to return.

5
00:00:17,280 --> 00:00:24,020
So to fix this up one way we could fix it is to add in a type invitation for coordinates so we need

6
00:00:24,020 --> 00:00:27,260
to add in a type invitation for an object.

7
00:00:27,410 --> 00:00:32,920
We already saw an example of that right back up here when we defined the object literal of points.

8
00:00:33,130 --> 00:00:38,510
So to add in a type annotation for an object right after the variable name were put in that colon and

9
00:00:38,510 --> 00:00:44,280
then the overall structure of that object so for us we're going to add in coordinates right here.

10
00:00:44,300 --> 00:00:49,310
I'll put in a colon then instead of curly braces and inside they're going to say this thing is going

11
00:00:49,310 --> 00:00:54,830
to have a property called X that is a number and it's going to have a property y that is a number as

12
00:00:54,830 --> 00:01:01,510
well so now we've given enough information to typescript that it can figure out what type of value coordinates

13
00:01:01,510 --> 00:01:03,300
is by now mouse over it.

14
00:01:03,310 --> 00:01:05,690
I see the type indentation on here.

15
00:01:05,690 --> 00:01:10,570
And now if I tried to reference say coordinates dot blah blah blah I'll very quickly see an error message

16
00:01:10,570 --> 00:01:15,130
that tells me that is not a property on that object okay.

17
00:01:15,170 --> 00:01:16,160
That's pretty much it.

18
00:01:16,190 --> 00:01:21,200
This is one of the three cases where we are going to add in type annotations anytime we call a function

19
00:01:21,380 --> 00:01:27,020
that returns type any adjacent dot pass is just one of the functions in javascript that returns type

20
00:01:27,020 --> 00:01:27,230
any.

21
00:01:27,230 --> 00:01:29,000
There are several others as well.

22
00:01:29,070 --> 00:01:32,030
It's will kind of see some those different functions over time.

23
00:01:32,030 --> 00:01:36,980
And in fact we might eventually have to write our own functions that return type any as well.

24
00:01:37,020 --> 00:01:37,220
All right.

25
00:01:37,250 --> 00:01:38,430
Let's take a quick pause right here.

26
00:01:38,460 --> 00:01:43,320
When we come back the next video we'll move on to the next example or the next case where we are going

27
00:01:43,320 --> 00:01:48,500
to add in a type annotation willingly so quick pause and I'll see you in just a minute.
