The Performance Revolution in JavaScript Tooling

Speed-obsessed devs cheer, skeptics say “we’ve seen this” while Bun fans crash the party

TLDR: Developers are rebuilding JavaScript tools in faster languages like Rust and Go to cut build times and boost reliability. Comments split between “finally faster” and “this isn’t new,” spar over NVM speed, demand Bun/Zed, and pitch native TypeScript; it matters because faster tooling means quicker apps and happier devs.

The article declares a speed coup: JavaScript tools are being rebuilt in faster languages like Rust, Go, and Zig so apps build quicker and crash less. The crowd? Instantly divided. One nitpicker swings in with “this has been true for a decade,” calling the whole “revolution” more rebrand than breakthrough. Meanwhile, the vibe around Rust’s “cult” gets meme-y, with some cheering on SWC and friends, and others rolling eyes at yet another “fastest ever” headline.

Then the thread explodes in side quests. A commenter says the Node version manager (NVM) is “instant” and only slow if you’re swapping versions all day, dunking on claims of sluggishness. Another drags Python into the ring, praising the new “uv” tool while roasting pip for hanging during installs, because nothing spices up a JavaScript fight like a Python cameo. The crowd also complains the piece skipped the speed poster children Bun and Zed, sparking a chorus of “where’s Bun?” Finally, one bold take pushes beyond tooling: write TypeScript and compile it straight to native code through Microsoft’s .NET engine (CLR) using “AOT” (ahead-of-time) compilation—promising safety and speed. The drama is pure internet: half “finally, faster,” half “calm down, this isn’t new,” all fueled by hot takes, benchmarks banter, and meme-worthy shout-outs.

Key Points

  • Developer tools in the JavaScript ecosystem are increasingly rewritten in systems languages like Rust, Go, and Zig.
  • Modern JavaScript applications have large, complex codebases that strain traditional JavaScript-based tooling.
  • Systems languages provide native performance, better memory management, and concurrency, improving reliability and scalability.
  • Rust’s popularity fosters a focus on correctness, speed, and user experience, accelerating innovation in tooling.
  • Projects such as SWC, ESBuild, BiomeJS, Oxc, FNM/Volta, and TypeScript in Go exemplify this performance-focused shift.
