fn_deferred

Fractured Nations Deferred is a deferred object library I developed with mobile games in mind. It is very light, compadible and easy to use.

Purpose: This library is to give Promise A Object support. If your site needs to support promises but also needs to support IE, so you can not use window.Promise. Jquery is nice, but it is heavy. FN_Deferred weighs in about 3kb. FN_Deferred is a great stable micro library. Give it a whirl.

Multiple callback methods!

However you prefer to get your deferred objects Callbacks we can do them all.
			
- You can pass the callbacks in.
var deferred = new Deferred(doneCallback, failCallback);

- You can register them like jquery
deferred.done(doneCallback).fail(failCallback).always(alwaysCallback);

- You can register them like traditional Promise A
deferred.then(doneCallback, failCallback);

- You can register them like window.Promise
deferred.then(doneCallback).catch(failCallback);	

Resolve or Reject Multiple arguments

var deferred = new Deferred();
deferred.done(function(result, result2)
{
	console.log("Result1: "+result+" Result2: "+result2);
}); 
deferred.resolve("A", "B");


var deferred = new Deferred();
deferred.fail(function(error, error2)
{
	console.log("error: "+error+" error2: "+error2);
}); 
deferred.reject("A", "B");

Check the status of the Deferred

var deferred = new Deferred();
var rejected = deferred.isRejected();
var resolved = deferred.isResolved();
var status = deferred.status();

Get the value of a resolved or rejected Deferred

var deferred = new Deferred();
var value = deferred.value;

Can easily replace Jquery! FN_Deferred Supports promise method.

var deferred = new Deferred();
return deferred.promise();
