++ increment operator
++expression
expression++
A pre-increment and post-increment unary operator that adds 1 to expression . The
expression
can be a variable, element in an array, or property of an object. The pre-
increment form of the operator (
++expression) adds 1 to expression and returns the
result. The post-increment form of the operator (
expression++) adds 1 to expression and
returns the initial value of
expression (the value prior to the addition).
The pre-increment form of the operator increments x to 2 (x + 1 = 2) and
returns the result as y:
var x:Number = 1;
var y:Number = ++x;
trace("x:"+x); //traces x:2
trace("y:"+y); //traces y:2
The post-increment form of the operator increments x to 2 (x + 1 = 2) and returns the
original value of
x as the result y:
var x:Number = 1;
var y:Number = x++;
trace("x:"+x); //traces x:2
trace("y:"+y); //traces y:1
