What Does Tail Recursion Mean?
Tail recursion is the act of calling a recursive function at the end of a particular code module rather than in the middle. A function is recursive if it calls itself. This programming concept is often useful for self-referencing functions and plays a major role in programming languages such as LISP.
Techopedia Explains Tail Recursion
In computer programming, a function that calls itself, either directly or indirectly, is a recursive function. When this call happens at the end of the function, it is called tail recursion. Usually, other calculations or procedures are done before the recursive call.
