Also 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はJavaScriptのライブラリー。Prototype.jsやRubyと同等の機能を備えるが、プロトタイプを拡張する代わりに関数型プログラミングを採用している。例えば、_.eachは提供されていればネイティブなforEachを、そうでない場合は互換性がある実装を使用する。
