Are there any good JavaScript 2d game engines?

Question

JavaScript

There are plans to develop a small game "for myself", in order to improve skills.
Need help finding a 2d engine that supports JavaScript. Unity3D is considered last, I have experience with it.
We tried to do it on Node Webkit, the option is good, but there are few tools for building the application and correct development, it is difficult to add various frameworks like BackboneJS and EmberJS.
The game will consist mostly of an interface, with no direct control of the movement of the character (forward-backward, right-left).
So, I will summarize the approximate requirements: something similar to Node Webkit (development is similar to creating a website), the main language is JavaScript. Similarity with Node Webkit is not required, but suddenly there is.

Answer 1

Cool enough - www.isogenicengine.com
Look also at Pixi.js (for example: habrahabr.ru/post/174603 ) My colleague made a game on phaser.io - he responded well, see also.
And if you want to devote a couple of days / evenings to the choice with a transition to the night, then here:

Answer 2

Very powerful - Cocos2d-js . Games can be made not only for the browser, but also for mobile phones.

Answer 3

I completely agree with Alexander Lozovyuk . I also made some 2D games with Pixi.js . It's quite easy to learn and has almost unlimited possibilities for creating 2D HTML+JS games. You can see for
yourself the possibilities .

Answer 4

Tell me, how in such games as for example this one: www.bbc.co.uk/cbbc/games/junior-vets-on-call-game
Implement cheat protection? More specifically, I'm interested in the complexity of this process compared to the creation of the game itself.
What has always stopped me from writing such games is that since it works on JS and in the browser, then any player can prescribe an unlimited amount of resources for himself.
Please do not kick for confusion.
