MooTools is a collection of JavaScript utilities designed for the intermediate to advanced JavaScript developer. It allows you to write powerful and flexible code with its elegant, well documented, and coherent APIs.

MooTools code is extensively documented and easy to read, enabling you to extend the functionality to match your requirements.

Open Source License
MooTools libraries are released under the Open Source MIT license which gives you the possibility to use them and modify them in every circumstance.

How to use?
MooTools Selectors 
Selectors for DOM Elements

// get elements by class  $$('.foo' ); // or even: document.getElements('.foo');  // selector with different elements  $$('div.foo, div.bar, div.bar a' ); // get a single element  document.getElement('div.foo' );
Ajax! 
MooTools uses a Class called Request.

// create a new Class instance  var  myRequest = new  Request({ url: 'getMyText.php' , method: 'get' , onRequest: function (){ myElement.set('text' , 'loading...' ); }, onSuccess: function (responseText){ myElement.set('text' , responseText); }, onFailure: function (){ myElement.set('text' , 'Sorry, your request failed :(' ); } }); // and to send it:  myRequest.send(data);
To send a form it can be even more simple!

myForm.send(); // optionally you can add/change the form properties  myForm.set('send' , {url: 'contact.php' , method: 'get' });
How to create new DOM elements 
A simple MooTools Element example.

// the short way  new  Element('div#bar.foo' ); // using the element constructor  new  Element('div' , { 'class' : 'foo' , id: 'bar'  });
Event handlers 
Attach events to be updated on what's happening!

// attach a click event o a element  myElement.addEvent('click' , function (){ alert('clicked!' ); }); // attach several events at a time  myElement.addEvents({ mouseover: function (){ alert('mouseover' ); }, click: function (){ alert('click' ); } });
You can also remove, fire or clone events!

// remove a event  myElement.removeEvent(type, fn);
MooTools Class 
A simple MooTools Class example.

var  Animal = new  Class({ initialize: function (age){ this .age = age; } }); var  Cat = new  Class({ Extends: Animal, initialize: function (name, age){ // calls initalize method of Animal class  this .parent(age); this .name = name; } }); var  myCat = new  Cat('Micia' , 20 ); alert(myCat.name); // alerts 'Micia'.  alert(myCat.age); // alerts 20.
