Calling a function from within itself is called recursion and the simple answer is, yes. But don’t let this instil any idea in your mind that it is run of the mill coding. It is not.

A called function performs a defined task and when its return statement is executed or when its function-ending closing brace is reached, it returns the program control back to the main program.
What is the difference between calling function and called function?
What is Calling a Function and a Called Function? The Function which calls another Function is called Calling Function and the function which is called by another Function is called a Called Function.
How to call nested functions JavaScript?
Steps: Define the outer function. Inside outer, define the inner function. Call the inner function from within the outer function.
