Javascript - Statement while Statement


The while statement is a pretest loop.

The loop condition is evaluated before the loop body has been executed.

Tt is possible that the body of the loop is never executed. Here's the syntax:


And here's an example:

var i = 0;
while (i < 10) {
   i += 2;

In this example, the variable i starts out equal to 0 and is incremented by two each time through the loop.

As long as the variable is less than 10, the loop will continue.
