? JavaScript for Loop

The for loop is one of the most commonly used loops in JavaScript. It allows you to run a block of code repeatedly for a fixed number of iterations.

? Syntax

for (initialization; condition; increment) {  // code to be executed repeatedly}

• initialization: executed once before the loop starts (usually sets a counter)

• condition: checked before each iteration; if true, loop continues

• increment: executed after each iteration (usually updates the counter)

? Example: Basic for Loop

for (let i = 0; i < 5; i++) {  console.log("Iteration number: " + i);}

Output:

Iteration number: 0Iteration number: 1Iteration number: 2Iteration number: 3Iteration number: 4

? Explanation

• let i = 0: Start with i at 0

• i < 5: Loop runs while i is less than 5

• i++: Increase i by 1 after each iteration

? Example: Looping Through an Array

const fruits = ["apple", "banana", "cherry"];for (let i = 0; i < fruits.length; i++) {  console.log(fruits[i]);}

Output:

applebananacherry

Would you like me to explain other loops like for...of or while next?
