How to use the return function value in another function without calling the first function?

Answer 1

I don't understand the question. Could you please link your code and give an example of what should happen?

Answer 2

As long as I know without calling a function you can't get return value as the code block is to be executed.

You can use a function as a parameter of other function, you'll get the return value as a parameter of the other function. This type of function of called callback function.
