checkout how conformant QuickJS is with the modern ES standards https://test262.report/ https://test262.report/ (especially compared with other engines developed by big teams and companies behind them) Fabrice Bellard is a genius, and I really don't like using this word.

> Fabrice Bellard is a genius Yeah, I read about a cool tech and half the time he's behind it. When I learned about the rocketman flying near an airport a few weeks ago I was surprised it wasn't him testing his new rocket engine 3d printed in his basement! ;)

Prodigies like him kind of scare me. I studied at the same place as where Adam Dunkels (behind e.g. uIP and Contiki, a networked OS requiring 30 KB RAM and 30 KB ROM despite a GUI) did and he was almost a mythological figure with stories of taking multiple classes at once with ease.

  Wow, I remember playing with contiki, protothreads and his uBasic interpreter. He said he was bored in an event and wrote uBasic. What?? I cant even Anything else u remember about him?

Seriously? Bellard is behind this too? Genius is definitely the right word here!

  It is more amazing given that QuickJS is not a single feat but a cumulation of his older projects, each of them is great by itself: - TCC [1]: Of course, QuickJS is not the first language implementation he's written. - Pi calculation [2]: Once the world record holder (and opening the era of pi computation in commodity PCs), this surely inspired his next great invention: - LibBF [3]: A good and small arbitrary-precision number library. I think LibBF is a byproduct of NumCalc [4], and he has probably seen a way to the full language implementation using LibBF later (the current version of NumCalc is indeed based on QuickJS, sharing the technique used in the current version of JSLinux [5]).

  Wow. I had no idea that both ffmpeg and qemu was two of the things Bellard created. https://smartbear.com/blog/test-and-monitor/fabrice-bellard-portrait-of-a-super-productive-pro/ https://smartbear.com/blog/test-and-monitor/fabrice-bellard-...

    The wonders of Bellard never cease. Another discovery for me was that he wrote LZEXE in 1989~90 when he was 17. I remember this program from my childhood.

    He has developed a ton of stuff! What I found particularly impressive is the PC Emulator developed in Javascript which runs Linux within a browser! https://bellard.org/jslinux/ https://bellard.org/jslinux/ You can actually run X-Windows, Windows 2000, FreeDOS etc in a browser using this. His implementation of 4G LTE purely in software is also pretty amazing. https://bellard.org/lte/ https://bellard.org/lte/ His other projects: https://bellard.org/ https://bellard.org/
