Quick Summary

In programming, iteration refers to the repetition of a sequence of steps. This is a fundamental control structure that allows computers to solve complex problems by repeating simple instructions as needed.1

Iteration is distinct from recursion, which is a technique where a function calls itself until a specific condition is met. While both achieve repetition, iteration typically involves loops, whereas recursion breaks a problem into smaller, self-similar subproblems. Iteration is a core concept for expressing algorithms and organizing information within computer programs.21
