How I built a modern website in 2021September 29th, 2021 — 34 min read For over half of 2021, I worked on a complete rewrite of kentcdodds.com. You're reading this on the rewrite of this site! Are you using dark mode or light mode? Have you signed in and selected your team yet? Have you tried to call into the Call Kent Podcast?

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 few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
With pen and paper, anyone can write a journal entry, draw a diagram, perform a calculation, or sketch a cartoon. Digital tablets like the iPad or reMarkable can adapt pen and paper into the world of digital media. In doing so, they trade away some of paper’s advantages like cheapness and tangibility. In exchange, we get new computational powers like nondestructive editing and ease of transmission

Today we’re excited to announce the availability of TypeScript 4.7! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript and adds syntax for types. Types help describe what kinds of values you’re working with and what kinds of functions you’re calling. TypeScript can use this information to help you avoid about mistakes like typos, missing arguments, or forgetting
Today we are excited to announce the beta release of TypeScript 4.7!

Object Structure in JavaScript EnginesFrom a developer's perspective, objects in JavaScript are quite flexible and understandable. We can add, remove, and modify object properties on our own. However, few people think about how objects are stored in memory and processed by JS engines. Can a developer's actions, directly or indirectly, impact performance and memory consumption? Let's try to delve i

Why is WebAssembly a second-class language on the web? – Mozilla Hacks - the Web developer blog
This post is an expanded version of a presentation I gave at the 2025 WebAssembly CG meeting in Munich. WebAssembly has come a long way since its first release in 2017. The first version of WebAssembly was already a great fit for low-level languages like C and C++, and immediately enabled many new kinds of applications to efficiently target the web. Since then, the WebAssembly CG has dramatically
Today we’re excited to announce the release of TypeScript 5.6! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by adding syntax for types. Types describe the shapes we expect of our variables, parameters, and functions, and the TypeScript type-checker can help catch issues like typos, missing properties, and bad function calls before we even run our code.

Toggle dark mode What follows is a brain dump of everything I know about compiling Rust to WebAssembly. Enjoy. Some time ago, I wrote a blog post on how to compile C to WebAssembly without Emscripten, i.e. without the default tool that makes that process easy. In Rust, the tool that makes WebAssembly easy is called wasm-bindgen, and we are going to ditch it! At the same time, Rust is a bit differe

Parsing SQL - Strumenta
The code for this tutorial is on GitHub: parsing-sql SQL is a language to handle data in a relational database. If you worked with data you have probably worked with SQL. In this article we will talk about parsing SQL. It is in the same league of HTML: maybe you never learned it formally but you kind of know how to use it. That is great because if you know SQL, you know how to handle data. However

Why XML Comments matter XML is a popular format for storing and sharing data. It was explicitly designed for people and programs to read and write data.[1] From spreadsheets to save states, most modern software and games parse and write XML.
