Introduction to JavaScript Loops

Loops are used to repeat a block of code for a specified number of times.

Step 1: Using the For Loop

The for loop is used to execute a block of code for a specified number of times.

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

Step 2: Using the While Loop

The while loop is used to execute a block of code as long as a condition is true.

let i = 0;
while (i < 5) {
    console.log(i);
    i++;
}

Step 3: Using the Do-While Loop

The do-while loop is used to execute a block of code at least once, and then repeat it as long as a condition is true.

let i = 0;
do {
    console.log(i);
    i++;
} while (i < 5);

By following these steps, you can use loops to repeat tasks in your JavaScript code.
