How to Create a While Loop in JavaScript ?

In JavaScript, you can create a while loop using the while keyword followed by a condition. The loop continues to execute as long as the specified condition evaluates to true.

Syntax:

while (condition) {
    // Code to be executed while the condition is true
    // The condition is checked before each iteration
}

Example: Here, the loop continues to execute as long as the counter is less than or equal to 5. The console.log(counter) statement prints the current value of the counter, and counter++ increments its value in each iteration.

Javascript

let counter = 1;

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