If we observe closely, there are several similarities between iteration and recursion. In recursion, a function performs the same set of operations repeatedly but with different arguments.

A loop does the same thing except that the value of the iterator and other variables in the loop’s body change in each iteration.

Figuring out which approach to use is an intuitive process. Many problems can be solved through both.

Recursion is useful when we need to divide data into different chunks. Iteration is useful for traversing data and also when we don’t want the program’s scope to change.
