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.
