The latest frameworks aren’t just “trends”, like fashion.
They’re improved ways of doing things. Better, simpler, more reliable.
Advocating to use tech that changes slowly, or avoid latest frameworks is advocating being slower and less productive.
I do think a lot of frameworks are fashion statements, but that’s okay because style matters when doing creative work.
They’re developers from other ecosystems who just want to look down in javascript and feel superior.
There’s only so many ways to write a reasonable GUI framework. There’s only so many ways to do general purpose data stores. There’s only so many ways to handle events. There’s only so many ways to schedule load/threads/work. There’s only so many ways to build code. There’s only so many ways to do object/class/etc. inheritance. There’s only so many ways to do interfaces/contracts/whatever. etc. It’s the same patterns and trade offs over and over again, but if you’ve never much of anything outside of web dev you’d never know that.
The past 15 years of web dev is the story of young programmers racing forward, having never bothered to look at the past.
