Any sane i18n options for JavaScript?


Although I like Aurelia in general, I have to admit their i18n process is rather complicated and inelegant.  This isn't Aurelia's fault -- I have yet to find any JavaScript library/framework that does a stellar job at localization/internationalization (especially for continuous builds/integration).  Any recommendations from my readers?

Update: I came across Localize.js and it works really well (although it's a commercial product so it may not be the right fit for everyone).
