Hell no they are welcome to this video on on to find datatype in Javascript a variable without value
is referred to as on defining it.
What is a variable.
Well in general computer programming and being javascript variables are used to store information which
can be referenced at a later time.
So where by a variable is created and does not have value.
It is referred to as on defined B on defined key word it can also be use to empty variable of its value.
So if you've got a variable that has a value you can also use the undefined key word to clear that value
in this quick video.
I explain what B on defined data type is in javascript.
It refers to a variable without value.
B are usually identified with the key word on defined.
So wherever you see a variable in javascript that hasn't been defined.
It will come up with the on defined key word.
Thank you so much for watching.
I hope the video has made sense.
If you happen please drop me a message and I will be more than happy to explain further.
Thank you.
Bye for now.
