AS3 If statement syntax shortcut

November 11, 2008 by jared

var v : Boolean = true;
var i : int;
v ? i = 0 : i = 1;

Is the same as

var v : Boolean = true;
var i : int;
if (v)
     i = 0;
else
     i = 1;

You wouldn’t believe this! Just yesterday I was looking for this

and you can do this too:

i = v ? 0: 1;

also try this:

v ? [ trace( "this" ), trace( " is true" ) ] : [ trace( "DOH!" ) ] ;

or how about:

var v = false;

var a = [ c, d ];
var b = [ d, c ];

v ? a.forEach(e) : b.forEach(e);

function c():void{ trace( “c” ) }
function d():void{ trace( “d” ) }
function e(…args):void{ args[0]() }

some more random stuff:

var v = “testing”;

v is String ? [ c(), d()] : [ d(), c() ];

function c():void{ trace( “c” ) }
function d():void{ trace( “d” ) }
