Nope, this is a bad take, parroted without understanding; if it got moved into the std lib, it was probably useful enough. You can even read why in the original proposal if you comb the archives enough (from https://github.com/tc39/proposal-string-pad-start-end):

> It is highly probable that the majority of current string padding implementations are inefficient. Bringing this into the platform will improve performance of the web, and developer productivity as they no longer have to implement these common functions.

“It’s too trivial” is not why left-pad was in the news. Go read about it to understand the actual issue: https://www.theregister.com/AMP/2017/07/12/javascript_spec_s...

The reason I say it's a strange example is because of this: https://github.com/tc39/proposal-string-pad-start-end, which was added to the language two years ago (and seemingly very quickly [as tc39 proposals go], I assume due to left-pad)

dalton likes to name methods as ecmascript itself, what I very much appreciate. padStart() was proposed as standard after lodash 3.0.0 was released. So he changed it on the next major release:
