another day, another javascript runtime environment

  as far as I'm aware Bun is significantly faster than others while maintaining a lot of the compatibility

    The problem of the JS ecosystem is not speed precisely.
• bigDinosaur 4y ago
  do we actually get many Javascript runtimes? Certainly fewer than JS frameworks.

  Is there really that many? Outside of browsers, I know of Node, Deno and now Bun. Is there really that many serious attempts to replace node?

    Bun is using the JavaScriptCore engine which is the Webkit/Safari Javascript engine. It is not written in Zig.
  • SahAssar 4y ago
    The engine (V8 analog) is not a "Zig engine", it's javascriptcore. The wrapper is Zig, like node is C/C++ and deno is Rust.

      My bad, their page says "Bun uses the JavaScriptCore engine, which tends to start and perform a little faster than more traditional choices like V8. Bun is written in Zig, a low-level programming language with manual memory management." I conflated these two.

  History is repeating once again. So let's face it: NodeJS is now the new Java. ;)

  Competition is a good thing. The javascript engines wouldn't be as fast as they are now if there was only one engine.

    Sometimes it not a good thing when it keeps people using JavaScript.

  we’ve done virtual dom (and better than virtual dom) UI frameworks to death so I guess this is next!
