Now

Now is a time toolkit for javascript

Overview

Now is inspire by Now(a time toolkit for golang). When I'm about to complete the code, I found that this is just a total toy. go's standard library time native support Format, Duration and so on. Format and i18n needs a huge amount of work. I found that moment had implemented them in a very elegant way. So I borrow it, respect and gratitude!
