You Don't Need Moment.js
I really don't understand this... while yes, I might at some point be interested in reducing my bundle size, for 99% of developers out there, a difference in 300kb is just completely irrelevant.I choose my JS libraries because they are actively maintained, have well designed APIs (easy to use), are common enough to where newly hired developers already know them, and just generally make my life easier.  This doesn't address any of that.
