Another factor is that we’re seeing the continued rise of massive front end frameworks at the same time that the native JavaScript environment is becoming faster and easier to use. There’s a non-trivial number of sites where the easiest thing to maintain will be standard JS/CSS rather than whatever was in vogue a few years before.

This is also of interest from the performance angle: frameworks take on a lot of expense maintaining certain levels of magic, convenience, and general applicability which has its benefits but also makes it easier to miss or fix problems. The first time I tried React on a serious project, the coworker who’d been hyperventilating about how fast the virtual DOM would be was surprised to learn that it was something like 40,000 times slower and that there was no easy way to fix it (innerHTML updates on rows in a large table when textContent was sufficient).

The last time I did a fresh project I ended up using just ES6 + SCSS and found it to be quite pleasantly rewarding. So many of the old tedious points have gone away with flexbox / grids, ES6 classes and arrow functions, querySelectorAll and the newer array methods, fetch vs. xhr, etc.
