while

while ( condition ) {
    Statements;
}

This keyword is used to repeat a block of code zero or more times. When the while statement is encountered the condition is evaluated. If the condition is true, the Statements in the while block are executed; otherwise control passes to the statement following the while block. If the condition is true, after the Statements have been executed, the condition is again evaluated, and the whole process repeats.

Example:

    var i = 10;
    while ( i > 0 ) {
        debug( i );
        i--;
    }

See also do, for, continue and break.
