From the time it was announced, WebAssembly caused a huge buzz in the front-end world. The web community readily embraced the idea of taking code written in programming languages other than JavaScript and running that code in the browser. Above all WebAssembly consistently guarantees native speeds much faster than JavaScript. At eBay, we were no different. Our engineers were very excited about thi
Toggle dark mode Can you use the DOM in WebAssembly? Rust says yes, other people say no. Before we can resolve that dissonnance, I need to shine some light on what raw WebAssembly can do. When you go to WebAssembly.org, the very first thing you see is that it’s a “stack-based virtual machine”. It’s absolutely not necessary to understand what that means, or even look at the WebAssembly VM specifica
It's consistently fast, yo In my previous articles I talked about how WebAssembly allows you to bring the library ecosystem of C/C++ to the web. One app that makes extensive use of C/C++ libraries is squoosh, our web app that allows you compress images with a variety of codecs that have been compiled from C++ to WebAssembly. WebAssembly is a low-level virtual machine that runs the bytecode that is
Created by @diekusThe web just got a lot faster with WebAssembly, the low-level assembly-like language and compile target. The standard has reached cross-browser consensus and WebAssembly is now available in the latest Beta version of Samsung Internet (v7.2.10.12). For more background info on Web Assembly, see the article on MDN Webdocs. WebAssembly brings near-native performance to the web. But,
Sometimes you want to use a library that is only available as C or C++ code. Traditionally, this is where you give up. Well, not anymore, because now we have Emscripten and WebAssembly (or Wasm)! The toolchain I set myself the goal of working out how to compile some existing C code to Wasm. There's been some noise around LLVM's Wasm backend, so I started digging into that. While you can get simple
Edit: Further algorithmic improvements yielded additional speedups over what is described here, for total speedups of up to 10.9x faster than the original implementation. Read about these extra gains in Speed Without Wizardry! Tom Tromey and I have replaced the most performance-sensitive portions of the source-map JavaScript Library’s source map parser with Rust code that is compiled to WebAssembl
Making WebAssembly even faster: Firefox’s new streaming and tiering compiler People call WebAssembly a game changer because it makes it possible to run code on the web faster. Some of these speedups are already present, and some are yet to come. One of these speedups is streaming compilation, where the browser compiles the code while the code is still being downloaded. Up until now, this was just

This is post # 6 of the series dedicated to exploring JavaScript and its building components. In the process of identifying and describing the core elements, we also share some rules of thumb we use when building SessionStack, a JavaScript tool for developers to identify, visualize, and reproduce web app bugs through pixel-perfect session replay. If you missed the previous chapters, you can find t
WebSight demonstrates a comparison of performance between JavaScript, asm.js, and WebAssembly. A user uploaded static image or live video is displayed for each target. Performance is measured by the length of time it takes to detect face(s) or eyes in the image or video. Each target is run in its own web worker. The popular open source computer vision library, OpenCV, was compiled using Emscripten
