I think this comment undervalues the quality of engineering that Evan has put into esbuild. It’s not only quick because it’s written in golang, but also due to the decisions taken in architecture and an opinionated tool that does mainly one thing well.
I don’t read OP as devaluing Evan’s work. Presumably the TypeScript/Webpack/etc teams are also doing great engineering work — but because they’re writing in JS, the performance ceiling is significantly lower.
