While Loop
In JavaScript, while loop is used to execute a block of code in a number of times as long as the specified condition is true. Here, the condition is checked every time at the beginning of the loop.
Syntax
While (condition)
{
Block of code
}
Code:
<html>
<body>
<h2>The While Loop</h2>
<script>
var x =1;
while(x<=5)
{
document.write(x + "<br>");
x++;
}
</script>
</body>
</html>In the above example, the first part is that the value of x is initialized as 1.
The second part is the condition in a while loop for that the program executes until the condition is not false like the value of x is 1 and block of code of while loop is executed until when the condition is not false means when the value is 6.
