RightJS is aimed at dynamic languages crowd, as such it does not have all the long names and complex class constructions like many other frameworks written by Java and C++ developers.
On one side RightJS has a really nice and simple, easy to write and read syntax that makes it a snap to use and extend even for noobs. An on the other, it supports multiple paradigms, has extensive OOP and FP abilities along with other features that will make any tough professional happy.
RightJS is a really compact framework of just 30k and as the matter of fact it already has several plugins backed in. It has everything any serious framework should have, dom manipulations handling, native units extensions, basic visual effects, extensive OOP abilities, AJAX, additional form features, cookies. You name it!
And RightJS is not just small by itself, it has a number of small and fast plugins, you can add them to the main build, or switch off unnecessary features stripping it down to the very skinny 18k core.
RightJS takes the performance issue very seriously, we do lots of regressive and performance testing to make sure all methods in the framework work just as fast as they possibly can.
RightJS reuses all native functionality every browser can provide and it doesn't overcomplicate things with too fancy, slow features. As the result, RightJS beats up all the modern frameworks in most of the routine operations, and in many cases gets really close the pure dom code performance.
