Comma Operator (,) (JScript 5.6) 

  • Article

Causes two expressions to be executed sequentially.


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, and obtains the value of the expression on the right. The most common use for the , operator is in the increment expression of a for loop. For example:

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.
