Hell no they are welcome to this video on on to find datatype in Javascript a variable without value

2
00:00:14,180 --> 00:00:18,600
is referred to as on defining it.

3
00:00:18,990 --> 00:00:21,090
What is a variable.

4
00:00:21,360 --> 00:00:31,740
Well in general computer programming and being javascript variables are used to store information which

5
00:00:31,740 --> 00:00:35,050
can be referenced at a later time.

6
00:00:35,600 --> 00:00:43,770
So where by a variable is created and does not have value.

7
00:00:43,830 --> 00:00:57,780
It is referred to as on defined B on defined key word it can also be use to empty variable of its value.

8
00:00:57,780 --> 00:01:05,650
So if you've got a variable that has a value you can also use the undefined key word to clear that value

9
00:01:07,860 --> 00:01:10,000
in this quick video.

10
00:01:10,200 --> 00:01:16,670
I explain what B on defined data type is in javascript.

11
00:01:16,770 --> 00:01:21,570
It refers to a variable without value.

12
00:01:22,020 --> 00:01:26,760
B are usually identified with the key word on defined.

13
00:01:26,880 --> 00:01:33,870
So wherever you see a variable in javascript that hasn't been defined.

14
00:01:33,870 --> 00:01:37,990
It will come up with the on defined key word.

15
00:01:38,400 --> 00:01:41,080
Thank you so much for watching.

16
00:01:41,130 --> 00:01:43,910
I hope the video has made sense.

17
00:01:44,070 --> 00:01:51,600

18
00:01:51,930 --> 00:01:52,860
