Same with PHP: its bad reputation was due the proliferation of terrible, insecure and unmaintainable code written by first time programmers (or should I say webmasters) in the early 2000s.

These days its Javascript and the horde of fresh faced web designers and React engineers that try and reinvent the wheel. I don't think the quality of JS engineers on average is that low, programming culture has improved a lot, but without real world experience one tends to both overengineer and underestimate the problem. The JS world is very brittle because of it, and because of a frankly terrible language.
