Yes I can. All of those except for facebook (because facebook is a sprawling platform) seem reasonable to be able to build without a build system. And with using es6 modules it's not "putting a script tag in HTML", you have a proper module loading system without needing any builds or libs.

I'm not saying it's some sort of lost knowledge like Damascus steel, I'm just saying that many people these days are so caught up into the current dogma of JS that they never consider a simpler but still modern path.
