How to while loop in JavaScript?, someone asked me to explain?

In this article we will discuss implementing while loop. The while statement creates a loop that executes a specific statement until the certain condition is met.

Syntax:

    while (condition) {
       // code block to be executed
    }

Example:

<script type="text/javascript">

    var targetNumber = Number(prompt("Please enter your target number", ""));
    var i = 0;
    while (i <= targetNumber) {
document.write(i + "<br/>");
        i = i + 2;
    }

  </script>
