Recursion is the process of defining something in terms of itself. The idea used by compilers to optimize tail-recursive functions is simple since the recursive call is the last statement, there is nothing left to do in the current function, so saving the current function's .

Here is the countdown function again, with a base case: It may not be obvious exactly what is happening in this function. 2^4 = 8*2 = 16 Concerning the "why you would use it": Does this matter to non-programmers? 1. Just what does the listener already understand? Music. The recursive function's structure can often be modeled after the definition of the recursive data structure it takes as an input. Recursive functions use something called the call stack. When a program calls a function, that function goes on top of the call stack. Communication and stakeholder relationships are crucial to the success of a data project. They can still re-publish the post if they are not suspended.
