##### Description

> Executes a statement until a specified condition is false.

##### Syntax

> while (expression)
> statement

> The while statement syntax has these parts:

> Part | Description
> expression | A Boolean expression checked before each iteration of the loop. If expression is true, the loop is executed. If expression is false, the loop is terminated.
> statement | The statement to be executed if expression is true. Can be a compound statement.

##### Remarks

> The while statement checks expression before a loop is first executed. If expression is false at this time, the loop is never executed.

> The following example illustrates the use of the while statement:

> >     function BreakTest(breakpoint)
> >     {
> >        var i = 0;
> >        while (i < 100)
> >        {
> >        if (i == breakpoint)
> >          break;
> >          i++;
> >        }
> >        return(i);
> >     }
