Hello While come to these video on not in Javascript all is referred to as nothing.

2
00:00:11,670 --> 00:00:16,240
It means value does not exist.

3
00:00:16,430 --> 00:00:21,740
It's also treated as an object to have a script.

4
00:00:21,840 --> 00:00:34,250
You can also set a value to Nong by emptying the value for example if you have a field for email addresses

5
00:00:34,890 --> 00:00:43,410
and the person has changed your email address and you can't get a hold of them you don't know what the

6
00:00:43,410 --> 00:00:45,350
new e-mail address is.

7
00:00:45,510 --> 00:00:49,530
Rather Don't kid the old value that you don't need.

8
00:00:49,530 --> 00:00:50,970
That does not work.

9
00:00:51,150 --> 00:00:58,140
You can set it to not so where you are preference in the e-mail address for that person.

10
00:00:58,140 --> 00:01:01,100
It will be not because it's empty.

11
00:01:01,170 --> 00:01:03,750
You dont know what it is.

12
00:01:03,810 --> 00:01:18,130
So in no value you can be used to empty an existing value or place where the value can not be determined.

13
00:01:18,150 --> 00:01:23,590
Just a quick summary of what I have covered in this video.

14
00:01:23,820 --> 00:01:25,530
It's a very quick video.

15
00:01:25,720 --> 00:01:34,140
A gnarled value in Javascript refers to a value that does not exist.

16
00:01:34,230 --> 00:01:45,460
They are identified with a key would not and also regarded as our guests within the javascript language.

17
00:01:45,750 --> 00:01:48,660
Thank you so much for watching.

18
00:01:48,690 --> 00:01:51,790
I hope you make sense.

19
00:01:51,830 --> 00:01:52,970
Bye for now.
