New generation of tools:

• Speedy Web Compiler
• ESBuild
• BiomeJS t combines code formatting and linting into a single high-performance JavaScript toolchain.
• Oxc is a collection of Rust-based Javascript tools focusing on linting, formatting and transforming Javascript and typescript tools.
• Fast Node Manager / Mise
• Typescript in Go

Another notable efforts are Turbopack and Turborepo, Bun and Deno.

Contributing becomes less accessible to the majority of JavaScript developers of course. The shift demonstrates other skills in system programming that will drive even more innovative tooling in the coming years
