Javascript While Loop

The while loop repeatedly executes a block of statements until a particular condition is true. It first checks the condition and executes a block of statements if the condition is true.

Syntax:

while(condition){
//Block of statements
}

JavaScript while loop example:

<html>
<head>
<script>
var num=1;
while (num<=10) {
document.write(num + "<br/>");
num++;
}
</script>
</head>
<body>
</body>
</html>
