not bad, a quick skim of the repo shows that the locale file sizes might be 50% or less as compared to Moment.js - approx. 1 kB per locale from day compared to 2+ kB per locale from moment

Why is this good/better compared to date-fns?

Smaller bundle size, similarity to moment.js

As a dev who’s used all three, is there a massive difference? Not really. Stick with what you like (though moment is no longer maintained so maybe not that)

Very awesome to see Moment JS have a legacy. What a great api

It's embarrassing we never evolved the date api which comes with the browser.

That said, I tend to err on writing a custom function / importing only a custom function over importing an entire library just to run a 2 lines function.

I have not used moment.js or other date libraries in a long while. But how does this compare to Luxon? (https://moment.github.io/luxon/#/why)

The new Temporal API in JS is precisely that.

Luxon is my preferred library
