Looping in JavaScript

Looping in JavaScript is useful when you want to perform the same task again and again without writing the same code repeatedly.

Types of loops

• for loop
• while loop
• do...while loop
• for...of loop
• for...in loop

These are the main looping constructs available in JavaScript.

While loop

A while loop in JavaScript repeats a block of code as long as a condition is true.
It is called an entry‑controlled loop because the condition is checked before the code runs.

let i = 0;
while (i

Important: If you forget to update the loop variable, the condition may never become false, resulting in an infinite loop.
