var z = (x < 6) ? x: y;
trace (z); // returns 5
The following example shows a conditional statement written in shorthand:
var timecode:String = (new Date().getHours() < 11) ? "AM" : "PM";
trace(timecode);
The same conditional statement could also be written in longhand, as shown in the following
example:
if (new Date().getHours() < 11) {
var timecode:String = "AM";
} else {
var timecode:String = "PM";
} trace(timecode);
-- decrement operator
--expression
expression--
A pre-decrement and post-decrement unary operator that subtracts 1 from the expression.
The expression can be a variable, element in an array, or property of an object. The predecrement
form of the operator (--expression) subtracts 1 from expression and returns
the result. The post-decrement form of the operator (expression--) subtracts 1 from the
expression and returns the initial value of expression (the value prior to the
subtraction).
Operands
expression : Number - A number or a variable that evaluates to a number.
Returns
Number - The result of the decremented value.
Example
The pre-decrement form of the operator decrements x to 2 ( x - 1 = 2) and returns the result
as y:
var x:Number = 3;
var y:Number = --x; //y is equal to 2
The post-decrement form of the operator decrements x to 2 (x - 1 = 2 ) and returns the
original value of x as the result y:
var x:Number = 3;
var y:Number = x--; //y is equal to 3
