JavaScript Loops

What is loops?

A loop is used to execute a block of code repeatedly until a specified condition becomes false.

Types of Loops in JavaScript

• for Loop
• while loop
• do while

for loop

The for loop is used when the number of iterations is known before the loop starts.

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

while Loop

A while loop executes a block of code repeatedly as long as the given condition is true.

let i = 1;

while (i <= 5) {
    console.log(i);
    i++;
}

do while Loop

A do...while loop executes the code once before checking the condition.

let i = 1;

do {
    console.log(i);
    i++;
} while (i <= 5);
