We are excited to announce the release of the new version of Prettier! We have made the migration to using ECMAScript Modules for all our source code. This change has significantly improved the development experience for the Prettier team. Please rest assured that when using Prettier as a library, you can still use it as CommonJS as well. This update comes with several breaking changes. One notabl

All JavaScript and TypeScript Features of the last 3 years
TypeScript as envisioned by Stable DiffusionThis article goes through almost all of the changes of the last 3 years (and some from earlier) in JavaScript / ECMAScript and TypeScript . Not all of the following features will be relevant to you or even practical, but they should instead serve to show what’s possible and to deepen your understanding of these languages. There are a lot of TypeScript fe

Reading Time: 9 minutes Phil Karlton has famously said that the two hardest things in computer science are naming things and cache invalidation1. That’s still kinda true in front-end development. Naming stuff is hard, and so is changing a class name when your stylesheet is cached. For quite a few years, I’ve had a gist called “Tiny Rules for How to Name Stuff.” Which is what you think: little tiny
WebKit Features for Safari 26.2
Safari 26.2 is a big release. Packed with 62 new features, this release aims to make your life as a web developer easier by replacing long-standing frustrations with elegant solutions. You’ll find simpler ways to create common UI patterns with just a few lines of HTML or CSS, and no JavaScript — like auto-growing text fields with CSS field-sizing, and buttons that open/close dialogs and popovers w
V8 Torque is a language that allows developers contributing to the V8 project to express changes in the VM by focusing on the intent of their changes to the VM, rather than preoccupying themselves with unrelated implementation details. The language was designed to be simple enough to make it easy to directly translate the ECMAScript specification into an implementation in V8, but powerful enough t

It is most common to use the validate method available on all incoming HTTP requests. However, we will discuss other approaches to validation as well
Documentation | Pipes
What Pipes is Pipes is a spiritual successor to Yahoo! Pipes, but if you did not know that site, you can think of Pipes as a visual programing editor specialized on feeds, or a visual shell, or simply as a glorified feed configurator. Pipes gives you blocks that can fetch and create feeds, and manipulate them in various ways. Think filtering, extracting, merging and sorting. All you need to do is
The simplicity of Prolog
Back to homepage Nowadays the most popular programming languages are Python, Javascript, Java, C++, C#, Kotlin and Ruby, and the average programmer is probably familiar with one or more of these languages. It's relatively easy to switch from one to another (barring any framework specific knowledge that may be needed), since they are all imperative (and for the most part object-oriented) languages,
Automated tests are important. Without them, programmers waste a huge amount of time manually checking and fixing their code. Unfortunately, many automated tests also waste a huge amount of time. The easy, obvious way to write tests is to make broad tests that are automated versions of manual tests. But they’re flaky and slow. Folks in the know use mocks and spies (I say “mocks” for short in this
