Note that John is a computer scientist that knows a fair bit about the Web: He had Node & npm installed, he knew what MIME types are, he could start a localhost when needed. What hope do actual novices have?
I think it’s even worse than that. Not only are potential new devs being put off ever getting started, I know plenty of devs with experience who have pushed out by the overwhelming and needless complexity of the modern web’s toolchain. It’s like a constant gaslighting where any expression of unease is summarily dismissed as being the whinings of “the old guard” who just won’t get with the programme.
John gives up. Concludes never to touch Node, npm, or ES6 modules with a barge pole.
(Just watch as Lea’s post gets written off as an edge case.)
