JScript for Statement

Executes a block of statements for as long as a specified condition is true.

for (initialization; test; increment)

statement

initialization

An expression. This expression is executed only once, before the loop is executed.

test

A Boolean expression. If test is True, statement is executed. If test if False, the loop is terminated.

increment

An expression. The increment expression is executed at the end of every pass through the loop.

statement

The statement to be executed if test is True. Can be a compound statement.

You usually use a for loop when the loop is to be executed a specific number of times as the following example demonstrates:

/* i is set to 0 at start, and is incremented by 1 at the end

of each iteration. Loop terminates when i is not less

than 10 before a loop iteration. */

for (i = 0; i < 10; i++)

{

j *= i;

}
