Comma Operator (,) (Windows Scripting - JScript)

 

Causes two expressions to be executed sequentially.

Syntax

expression1, expression2

Arguments

  • expression1
    Any expression.

  • expression2
    Any expression.

Remarks

The , operator causes the expressions on either side of it to be executed in left-to-right order. The most common use for the , operator is in the increment expression of a for loop. For example:

j=25;
for (i = 0; i < 10; i++, j++)
{
   k = i + j;
}

The for statement only allows a single expression to be executed at the end of every pass through a loop. The , operator is used to allow multiple expressions to be treated as a single expression, thereby getting around the restriction.
