JavaScript for Loop (Live Playground)

In this tutorial, we will explore the for loop, and learn how to use it in our code to help perform repetitive tasks.

for Loop

A for loop is used to execute a block of code a specific number of times. It consists of an initialization, a condition, and an update expression.


for (let i = 0; i < 5; i++) {
console.log(`Iteration ${i + 1}`);

In the example above, the loop will run 5 times, and the output will display the iteration number from 1 to 5.
