Recursion: a function that calls itself.

Recursion in computer science is a method where the solution to a problem depends on solutions to smaller instances of the same problem. Most computer programming languages support recursion by allowing a function to call itself within the program text. Some functional programming languages do not define any looping constructs but rely solely on recursion to repeatedly call code.

USE: we can use recursion for iteration
