One of 2023’s biggest trends for web tooling was rewriting existing tooling in Rust. Rust is a wonderful programming language that allows for shockingly fast binaries which still interop well with other web tools courtesy of WebAssembly. The speedups seen in tools such as swc and Turbopack are very exciting for fast development experiences.

But! It’s a misconception to think that Rust-based linters are a complete and total replacement for ESLint today. There are always tradeoffs when switching tooling. In this case, the positive performance advantages come with a negative feature gap: type-checked linting.
