Causes two expressions to be executed sequentially.
expression1, expression2The , operator syntax has these parts:
Part Description expression1 Any expression. expression2 Any expression.
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: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.for (i = 0; i < 10; i++, j++) { k = i + j; }
