Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill. A poorly phrased

31st December 2024 A lot has happened in the world of Large Language Models over the course of 2024. Here’s a review of things we figured out about the field in the past twelve months, plus my attempt at identifying key themes and pivotal moments. This is a sequel to my review of 2023. In this article: The GPT-4 barrier was comprehensively broken Some of those GPT-4 models run on my laptop LLM pri
JSON.stringify is a core JavaScript function for serializing data. Its performance directly affects common operations across the web, from serializing data for a network request to saving data to localStorage. A faster JSON.stringify translates to quicker page interactions and more responsive applications. That’s why we’re excited to share that a recent engineering effort has made JSON.stringify i
V8’s end-tier optimizing compiler, Turbofan, is famously one of the few large-scale production compilers to use Sea of Nodes (SoN). However, since almost 3 years ago, we’ve started to get rid of Sea of Nodes and fall back to a more traditional Control-Flow Graph (CFG) Intermediate Representation (IR), which we named Turboshaft. By now, the whole JavaScript backend of Turbofan uses Turboshaft inste
I’m a fairly frequent Hacker News lurker, especially when I have some other important task that I’m avoiding. I normally head to the Active page (lots of comments, good for procrastination) and pick a nice long discussion thread to browse. So over time I’ve ended up with a good sense of what topics come up a lot. “The Bay Area is too expensive.” “There are too many JavaScript frameworks.” “Bootcam
We've talked quite a bit about linting in the past two posts of this series, so I thought it's time to give eslint the proper limelight it deserves. Overall eslint is so flexible, that you can even swap out the parser for a completely different one. That's not a rare scenario either as with the rise of JSX and TypeScript that is frequently done. Enriched by a healthy ecosystem of plugins and prese
Toggle dark mode Add WebAssembly, get performance. Is that how it really works? The incredibly unsatisfying answer is: It depends. It depends on oh-so-many factors, and I’ll be touching on some of them here. Why am I doing this? (You can skip this) I really like AssemblyScript (full disclosure: I am one of their backers). It’s a very young language with a small but passionate team that built a cus
Node.js
Notable changes Add support for externally shared js builtins By default Node.js is built so that all dependencies are bundled into the Node.js binary itself. Some Node.js distributions prefer to manage dependencies externally. There are existing build options that allow dependencies with native code to be externalized. This commit adds additional options so that dependencies with JavaScript code

The Alkyne GC · mcyoung
Alkyne is a scripting language I built a couple of years ago for generating configuration blobs. Its interpreter is a naive AST walker1 that uses ARC2 for memory management, so it’s pretty slow, and I’ve been gradually writing a new evaluation engine for it. This post isn’t about Alkyne itself, that’s for another day. For now, I’d like to write down some notes for the GC I wrote3 for it, and more
How Rolldown Works: Symbol Linking, CJS/ESM Resolution, and Export Analysis Explained
How Rolldown Works: Symbol Linking, CJS/ESM Resolution, and Export Analysis Explained Introduction Rolldown is a high-performance JavaScript bundler written in Rust. While offering full compatibility with the Rollup API, it achieves bundling speeds 10 to 30 times greater. Driven by the need for a single, unified engine for both development and production, the Vite team is developing Rolldown to be
UPDATED: 2025-02-15: Fixed some bugs in the examples and pointed out that you don't usually just want to panic on memory allocation failure. I've been writing a lot of Rust recently, and as anyone who has learned Rust can tell you, a huge part of the process of learning Rust is learning to work within its restrictive memory model, which forbids many operations that would be perfectly legal in eith
The Humble For Loop in Rust By Martijn Faassen • 2024-12-11 • Tags: programming, rust Rust has some really nice functional programming facilities built in, all around an iterator concept. Rust being focused on performance and low level control makes it possible to use this without paying a performance cost. Sometimes I still prefer to use the humble for loop though. In quite a few cases, it combin
How fast is javascript? Simulating 20,000,000 particles The challenge, simulate 1,000,000 particles in plain javascript at 60 fps on a phone using only the cpu. Let's go. Ok, this is not a particularly difficult challenge if you did all the work on a gpu but the rule of the challenge is to use the CPU only or as much as possible and to stay in js land so no wasm. I know what you are thinking. This
Casual Parsing in JavaScript August 16, 2021 Over the last year and a half I've gotten really into writing parsers and parser-adjacent things like interpreters, transpilers, etc. I've done most of these projects in JavaScript, and I've settled into a nice little pattern that I re-use across projects. I wanted to share it because I think it's neat, and it's brought me joy, and it could be an intere
