Loop
A loop is a sequence of statements, loop body, which is executed a number of times based on runtime state. The body is executed once for each item of a collection (definite iteration), until a condition is met (indefinite iteration), or infinitely. A loop inside the loop body is called a nested loop.123 Early exit from a loop may be supported via a break statement.45
In a functional programming language, such as Haskell and Scheme, both recursive and iterative processes are expressed with tail recursive procedures instead of looping constructs that are syntactic.

Loop (statement)
In computer programming, a loop is a control flow construct that allows code to be executed repeatedly, usually with minor alterations between repetitions. Loops can be used to perform a repeated action on all items in a collection, or to implement a long lived program.
