underscorejs

Underscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby), but without extending any of the built-in JavaScript objects.

Description

JavaScript projects can use collection, object, and functional helpers without modifying built-in objects. This is useful for legacy codebases, browser projects, and scripts that were written around the Underscore API.

The package is a developer library, not an application. New projects may prefer native JavaScript or smaller focused utilities, but existing projects may still need API compatibility.
