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.

A complete Test Suite is included for your perusal.
