1
00:00:00,090 --> 00:00:04,830
D afraid of h the spread operators the sprint operator.

2
00:00:04,890 --> 00:00:05,230
Yes.

3
00:00:05,310 --> 00:00:10,920
You will sort of pull the value from an array or extract the properties from an object.

4
00:00:11,100 --> 00:00:23,610
For example if we create an oil way which contains the value of 1 3 5 and we also create a new array

5
00:00:26,940 --> 00:00:29,610
which contains 2 and 4.

6
00:00:29,610 --> 00:00:35,230
If we want to also add the where the 0 from the 0 away we have to use the.

7
00:00:35,250 --> 00:00:35,930
Operator

8
00:00:39,810 --> 00:00:46,350
and then add the 2 and 4 behind and then we try to print out the new away.

9
00:00:54,060 --> 00:01:02,700
Now you can say we contained or the three values from the 0 away and also the 0 The deal values which

10
00:01:02,700 --> 00:01:06,330
is 2 and 4 mastic the object as an example

11
00:01:10,350 --> 00:01:12,600
if the 0 object which contains

12
00:01:16,320 --> 00:01:18,870
a name which is Peter

13
00:01:22,510 --> 00:01:27,840
then height is one hundred and seventy five.

14
00:01:28,200 --> 00:01:38,160
Now if the new object want to have the 0 object properties we have to use this special operator and

15
00:01:38,160 --> 00:01:42,630
then add the properties that we want to add.

16
00:01:42,660 --> 00:01:49,140
For example we have H now if we print out a new object

17
00:01:54,790 --> 00:01:57,850
you can see it contained the name height and also the H.

18
00:01:59,290 --> 00:02:01,840
But if you is not the age.

19
00:02:01,870 --> 00:02:09,640
This is the height for example this is height and the one hundred and eighty eight become updated values

20
00:02:09,940 --> 00:02:18,190
rather than adding the new properties the spread operator not only applied on the array and object it

21
00:02:18,220 --> 00:02:31,150
also can be used in the function.

22
00:02:31,230 --> 00:02:38,850
Now you can see the bump up all arguments this is used to when you do not sure how many arguments do

23
00:02:38,850 --> 00:02:39,690
you have.

24
00:02:39,690 --> 00:02:49,770
You can use but but thought for example if we have one argument one permit us you can see it can print

25
00:02:49,770 --> 00:02:51,690
out the apple

26
00:02:54,320 --> 00:02:58,450
and if we continue add another string

27
00:03:02,830 --> 00:03:11,950
we should change it too I'd give you a print out all range and if we continue to add banana it will

28
00:03:11,950 --> 00:03:14,380
also open out in console

29
00:03:17,160 --> 00:03:24,990
cases because we're using portable argument each time we add the word deal it will become an array so

30
00:03:24,990 --> 00:03:29,520
we can for loop to a loop fluid of values and print out in the console.
