I think the same about Javascript, though the specifics are different. I've been writing JS for years, but I've been moving away from it lately because increasingly I feel like an odd duck in the JS world. Most javascript programmers have much less experience (in any language) than I do. When I mention I write a lot of javascript professionally, people assume I'm an fresh faced bootcamp grad. Its sometimes hard to find high quality libraries on npm because the average quality there is reasonably low. Eg good luck finding a password generator which doesn't use Math.random(). Or finding an email parsing library which preserves the order of email headers. (This has semantic content!)

Does there exist high quality java + javascript code? Sure. But even macdonalds makes good food sometimes. That isn't enough to make me a regular customer.

Sometimes the right call is to fight for the ecosystem you're a part of and help it improve. I've done a lot of that. But you don't have to fight for high quality software if you just go where the high quality software is being made. Its easier to switch languages than change a culture.

... I'm being a bit sloppy and judgemental here. Maybe it would be better to say, each ecosystem has a set of values. Javascript values programming velocity, accessibility to new programmers and simplicity. Java has a different list. Insomuch as you're living inside an ecosystem, you don't get to simply ignore and dismiss those influences when you don't like them. It sucks writing Go if you hate gofmt. It sucks writing rust if you don't even want the borrow checker. And it sucks writing Java if you hate dealing with AbstractIteratorFactoryImpl. Even if there's some redeeming code in openjdk.
