Underscore.js
Sign in to saveAlso known as Underscore
Underscore.js is a JavaScript library which provides utility functions for common programming tasks. It is comparable to features provided by Prototype.js and the Ruby language, but opts for a functional programming design instead of extending object prototypes. The documentation refers to Underscore.js as "the tie to go along with jQuery's tux, and Backbone.js' suspenders." Underscore.js was created by Jeremy Ashkenas, who is also known for Backbone.js and CoffeeScript.

Underscore.js is a JavaScript library which provides utility functions for common programming tasks. It is comparable to features provided by Prototype.js and the Ruby language, but opts for a functional programming design instead of extending object prototypes. The documentation refers to Underscore.js as "the tie to go along with jQuery's tux, and Backbone.js' suspenders." Underscore.js was created by Jeremy Ashkenas, who is also known for Backbone.js and CoffeeScript.
== History == Jeremy Ashkenas created Underscore by the end of 2009 as a spin-off from the DocumentCloud project, together with Backbone.js. It was one of the earliest libraries for JavaScript to provide general functional programming utilities, taking inspiration from Prototype.js, Oliver Steele's Functional JavaScript, and John Resig's Micro-Templating.
