3 Librerie js/jquery da conoscere

Ho messo da parte questi 3 link con l’intento di guardarli in un secondo momento con più attenzione.
Ovviamente non sono ancora riuscito a farlo ma voglio almeno condividerli facendo almeno un copie ed incolla della loro descrizione.

Qualcuno le ha già usate?

 

• jQuery++I am an MIT licensed collection of extremely useful DOM helpers and special events for jQuery 1.7 and later. I’m not a UI project like jQuery UI or jQuery Tools. Instead, I’m all about providing low-level utilities for things that jQuery doesn’t support. If Underscore is jQuery’s functional-programming tie, I am jQuery’s bald-spot covering toupee.http://jquerypp.com
• Underscore.jsUnderscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby), but without extending any of the built-in JavaScript objects. It’s the tie to go along with jQuery’s tux, and Backbone.js’s suspenders.Underscore provides 60-odd functions that support both the usual functional suspects: map, select, invoke — as well as more specialized helpers: function binding, javascript templating, deep equality testing, and so on. It delegates to built-in functions, if present, so modern browsers will use the native implementations of forEach, map, reduce, filter, every, some and indexOf.

• Backbone.jsBackbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interfacehttp://backbonejs.org
