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.

Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.

Getting started

Install by adding the ArchStrike repository to an existing Arch Linux install, then `pacman -S underscorejs`. See the official ArchStrike package listing and upstream homepage linked above for details.
