JavaScript JIT compiler
This playlist contains videos where I worked on the JIT (just-in-time) compiler for Ladybird's JavaScript engine (LibJS)

Ladybird: A new cross-platform browser project
This post describes the Ladybird browser, based on the LibWeb and LibJS engines from SerenityOS. Since starting the SerenityOS project in 2018, my goal has been “to build a complete desktop operating system to eventually use as my daily driver”. What started as a little therapy project for myself has blossomed into a huge OSS community with hundreds of people working on it all over the world. We’v
1. Techempower Rankings
25 October 2020 On Javascript Performance 1. Techempower Rankings by billwhizz Why is Javascript in the top 2 of techempower? This question was recently asked on github, prompted by the arrival of a new javascript platform near the summit of the intermediate techempower rankings. This platform, Just(js), is something I have been hacking on as a side-project for some time now. Here I will attempt t
GitHub - MTG/essentia.js: JavaScript library for music/audio analysis and processing powered by Essentia WebAssembly
Essentia.js is a JavaScript (JS) library for music/audio signal analysis and processing developed at the Music Technology Group, UPF, Barcelona. The core of library is powered by Essentia C++ library back-end using WebAssembly built via Emscripten along with a high-level JS and TypeScript API and add-on utility modules. ie, You can run an extensive collection of music/audio processing and analysis
GitHub - GoogleChromeLabs/webm-wasm: webm-wasm lets you create webm videos in JavaScript via WebAssembly.
webm-wasm lets you create webm videos in JavaScript via WebAssembly. The library consumes raw RGBA32 buffers (4 bytes per pixel) and turns them into a webm video with the given framerate and quality. This makes it compatible out-of-the-box with ImageData from a <canvas>. With realtime mode you can also use webm-wasm for streaming webm videos. Works in all major browsers (although Safari can’t play
GitHub - google/diff-match-patch: Diff Match Patch is a high-performance library in multiple languages that manipulates plain text.
The Diff Match and Patch libraries offer robust algorithms to perform the operations required for synchronizing plain text. Diff: Compare two blocks of plain text and efficiently return a list of differences. Diff Demo Match: Given a search string, find its best fuzzy match in a block of plain text. Weighted for both accuracy and location. Match Demo Patch: Apply a list of patches onto plain text.
GitHub - felixhao28/JSCPP: A simple C++ interpreter written in JavaScript
As far as I know, every public online C++ excuting environment requires backend servers to compile and run the produced executable. A portable and lightweight interpreter that can be run in browsers can be a fine substitute for those who do not intend to pay for such services. I also want to make a strict interpreter. The reason being C++ has too many undefined and platform-dependent behaviors and
部分文字列とRegExpの領域の冒険 | POSTD
パート1：小さな部分文字列はでき”ない” 数週間前、Dart SDKに関して、 String.substring のパフォーマンスが非常に悪い というバグが報告されました。以下は、その問題と一緒に提出されたマイクロベンチマークの中心部分です。 // JavaScript version function test(s){ console.time("substring(js)"); while (s.length > 1) { s = s.substring(1); } console.timeEnd("substring(js)"); } // Dart version test(s) { final stopwatch = new Stopwatch()..start(); while (s.length > 1) { s = s.substring(1); } print("subs
How V8 optimises JavaScript code?
I suppose, some of you heard that JavaScript executes as fast as C++. Some of you don’t understand how it’s even possible. JavaScript is a dynamically-typed language with Just in Time (JIT) compilation, when C++ is static-typed language with Ahead of Time (AoT) compilation. And somehow, optimised JavaScript code executes a little bit slower than C++ or even with the same speed. To understand why t

Getting started with Emscripten - Transpiling C / C++ to JavaScript / HTML5 - Dave Voyles | Software Engineer, Microsoft
Dave Voyles | Software Engineer, Microsoft Data science, game development, and financial services UPDATED: 2/2/16 I have a video overview for all of this now, too. Writing code for multiple platforms can be a lot of work. It can be even more work to have to completely rewrite it for each one, too. What if you wrote an application in C++, but wanted it to be displayed in the browser somehow? Well n
