Depends HOW you coded. I started JS at 11 yo in 2001, and became fulltime around 2012 - 2 more years of JS than you, I'm your grandaddy in this ever changing mess... I do not know Broccoli either. Googling it: "A fast, reliable asset pipeline, supporting constant-time rebuilds and compact build definitions" I raise my eyes to the ceiling and whine "why the hell isn't there an Oracle or IBM for JS to finally standardize just building crap".
It's probably cause I switched 4 years ago from the typical perma-migration grind to rarely using any framework and coding JS like I code the backend. Simple service classes in pure JS, rare dependencies, simple build. I once ditched years of work by a team of 40 to rewrite "everything" in low level javascript and showed the guys that what we spent all this years writing, really, was useless: did we need that enormous angular runtime config resolver that would draw generic components reading from crafted json configuration ? Or could we just write the damn things as we mean it in... javascript directly ?
Don't use a JS framework as long as you can help it, just the simple fact you can trace the whole function chain in a few seconds, vs reverse engineering the damn VueJS, or React, or Angular (does that monster even exist anymore, we hear about it a lot less than when it was all-encompassing, 8 years ago) plumbing, is worth it.
And son, if you want some war stories from your granddad, have you heard of jQuery ? :D
