for Loops

A for...of loop runs its block once for every item in an array or string — the modern, idiomatic way to loop over a sequence of values.

Syntax

for (const item of sequence) {
    // ...
}

Example

const fruits = ["apple", "banana", "cherry"];

for (const fruit of fruits) {
    console.log(fruit);
}

Expected output

apple
banana
cherry

The classic C-style loop (for (let i = 0; i < n; i++)) still works and is useful when you need the index itself, but for...of is preferred when you just need each value.

Practice

Log each number from 1 to 5 (inclusive) using a for loop.

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