In this article we will discuss implementing for loop. For statement creates a loop it consist of three optional expressions separated by semicolons. If the condition is true then the code executed inside the loop, otherwise the control will be out of the loop. The iteration statement where we can increase or decrease count.
Syntax:
for (statement 1; statement 2; statement 3) {
//code block to be executed
}
Example:
<script type="text/javascript">
var targetNumber = Number(prompt("Please enter your target number", ""));
for (var start = 0; start <= targetNumber; start ++)
{
document.write(start + "<br/>");
}
</script>
