Global variable!

Question

How to make a variable global??

Answer 1

If I am not wrong you mean," can I use a var that is inside a function and call it outside a function?"
I don't think you can. Because of how javascript, and most languages, scope variables, you can't access variables declared inside a function from outside a function. The variable belongs to the function's scope only, not the global scope.

Btw, you don't even need that. If you declare it globally(at the beginning of your code), you can access it from a function and change it and also call outside the function.

Answer 2

In js, A variable is by default global so you can call them from function:
