Description

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

Syntax

for (initialization; test; increment)
    statement

The for statement syntax has these parts:

Part	Description
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.

Remarks

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

/* 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. */
var myarray = new Array();
for (i = 0; i < 10; i++) 
{                        
  myarray[i] = i;                
}
