Hello While come to these video on not in Javascript all is referred to as nothing.
It means value does not exist.
It's also treated as an object to have a script.
You can also set a value to Nong by emptying the value for example if you have a field for email addresses
and the person has changed your email address and you can't get a hold of them you don't know what the
new e-mail address is.
Rather Don't kid the old value that you don't need.
That does not work.
You can set it to not so where you are preference in the e-mail address for that person.
It will be not because it's empty.
You dont know what it is.
So in no value you can be used to empty an existing value or place where the value can not be determined.
Just a quick summary of what I have covered in this video.
It's a very quick video.
A gnarled value in Javascript refers to a value that does not exist.
They are identified with a key would not and also regarded as our guests within the javascript language.
Thank you so much for watching.
I hope you make sense.
Bye for now.
