What is Underscore?

A JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.

Underscore is a JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects. It’s the answer to the question: “If I sit down in front of a blank HTML page, and want to start being productive immediately, what do I need?” … and the tie to Go along with jQuery’s tux and Backbone’s suspenders.

Underscore provides over 100 functions that support both your favorite workaday functional helpers: map, filter, invoke — as well as more specialized goodies: function binding, JavaScript templating, creating quick indexes, deep equality testing, and so on.
