Did anyone else notice the pattern that ever since the LLMs got popular the "I hate javascript" kind of posts or comments have decreased?

It could be attributed also to typescript dominance of course, since people don't use plain js anymore.

As for the blog post, I agree, I also implemented my own js framework when I code in vanilla js and it works fine.

The problem is not inventing frameworks, the problem is that everyone invents frameworks, so people all know different things and they are hard to hire.

I think the complaints attenuated in the last in the last 10-15 years because javascript itself became a much better language. Things really started to change with ES5. The introduction of let / const, modules, async, .?, template strings, etc. transformed it from an ugly kludge to a really capable language.

Of course, if you use old syntax you still deal with weird scoping and casting, but you don't have to any more.

Also, I think the framework churn has slowed considerably in the last 5 years.
