The Tiobe index might not be the best, but these are certainly popular languages and they don’t have decades, plural, of language warts.

Languages like Rust, Dart, Go, Kotlin, and Swift emerged when standard tooling was already expected, such as LSP, standard formatting and linting.

I don’t have experience with all of these languages, but I know that Rust and Darr have great tooling maintained by the same people who maintain the language and I can just pick any code editor with LSP support and I can expect the experience to be great.
