GitHub - krausest/js-framework-benchmark: A comparison of the performance of a few popular javascript frameworks
Currently there are 186 implemenations in this repository. It's of course impossible for me to make a security assessment for all those implementations. npm ci and npm install can execute arbitraty commands, so they should be executed only for packages you trust. Consequently I build on a dedicated virtual private linux server such that I don't have to install the packages for all those implemenat
Compile and run C in JavaScript | Bun Blog
From compression to cryptography to networking to the web browser you're reading this on, the world runs on C. If it's not written in C, it speaks the C ABI (C++, Rust, Zig, etc) and is available as a C library. C and the C ABI are the past, present, and future of systems programming. That's why in Bun v1.1.28, we introduced experimental support for compiling and running native C from JavaScript

The State of ES5 on the Web — Philip Walton
In 2017, I wrote an article showing web developers how they could deploy ES6+ code (a.k.a. ES2015) to production, without needing to transpile it to ES5. This technique was liberating for website developers who wanted the freedom to write modern code without having to worry about transpiler or polyfill bloat. Unfortunately, while many website developers were able to use this technique, most JavaSc
The web’s clipboard, and how it stores data of different types
The web’s clipboard, and how it stores data of different types If you’ve been using computers for a while, you probably know that the clipboard can store multiple types of data (images, rich text content, files, and so on). As a software developer, it started frustrating me that I didn’t have a good understanding of how the clipboard stores and organizes data of different types. I recently decided

Evading JavaScript Anti-Debugging Techniques
Debuggers serve as invaluable tools that empower developers to halt code execution and thoroughly analyze its behavior at any given moment. By utilizing a debugger, developers can efficiently identify and resolve issues within their code, making it an indispensable part of their toolkit. Chromium's dev tools debugger Debuggers are equally valuable tools for reverse-engineers, especially when deali
Fine-Grained Reactivity in Svelte 5 – Frontend Masters Boost
Fine-Grained Reactivity in Svelte 5 August 14, 2024 We’ve been looking at the up and coming Svelte 5. We looked at basic features like state, props, and side effects. Then we looked at Snippets, which is a lightweight feature Svelte added for re-using bits of HTML within (for now) a single component. In this post, we’ll take a close look at Svelte’s new fine-grained reactivity. What is fine-graine
Crafting a 13KB Game: The Story of Space Huggers
One of my favorite game jams is the legendary Js13kGames competition, where participants have one month to make a web browser game that fits in a 13 kilobyte zip file. To put that into perspective, a floppy disk from the before times could hold 1.44 MB, enough to fit over 100 JS13K games! In 2021 the contest celebrated its 10th annual event. The theme was “Space” and there were an impressive 223 g
HTML Web Components Can Have a Little Shadow DOM, As A Treat | Scott Jehl, Web Designer/Developer

But a little idea about HTML Web Components has been squatting in my brain for a little while and I needed a place to put it. There's been a lot of great writing about HTML Web Components in the past year, and as
Garbage collection and closures
Me, Surma, and Jason were hacking on a thing, and discovered that garbage collection within a function doesn't quite work how we expected. function demo() { const bigArrayBuffer = new ArrayBuffer(100_000_000); const id = setTimeout(() => { console.log(bigArrayBuffer.byteLength); }, 1000); return () => clearTimeout(id); } globalThis.cancelDemo = demo(); With the above, bigArrayBuffer is leaked fore
