I love how simple it was to add my custom currency format strings into this plugin, and how flexible you can make your UI! It's hard not to like something that lets you create any number of functions without having to write them yourself! The only thing I dislike about this plugin are some of their license requirements - they have to be hosted at www.numeraljs.com which isn't open source (and also requires registration). That said, with those restrictions in place, I don't see anyone being able to take over or replace all future functionality without paying for support from the original developers. We've been using this since version 1.6.2, and haven't had issues with our users until now. To make sure our users never run into problems again, we're switching out the package completely so none of our customers will ever encounter an issue while using numeral. In addition, we'll likely move off of jQuery.
