jQuery 4.0.0 has been in the works for a long time, but it is now ready for a beta release! There’s a lot to cover, and the team is excited to see it released. We’ve got bug fixes, performance improvements, and some breaking changes. We removed support for IE<11 after all! Still, we expect disruption to be minimal. Many of the breaking changes are ones the team has wanted to make for years, but co

This post is part of a collection on UUIDs. What is IDOR? Indirect Object Reference (IDOR) occurs when a resource can be accessed directly by its ID even when the user does not have proper authorization to access it. IDOR is a common mistake when using a separate service for storing files, such as a publicly readable Amazon S3 bucket. The web application may perform access control checks correctly

Fish 4.0: The Fish Of Theseus
About two years ago, our head maintainer @ridiculousfish opened what quickly became our most-read pull request: #9512 - Rewrite it in Rust Truth be told, we did not quite expect that to be as popular as it was. It was written as a bit of an in-joke for the fish developers first, and not really as a press release to be shared far and wide. We didn’t post it anywhere, but other people did, and we go
I use Claude Code. A lot. As a hobbyist, I run it in a VM several times a week on side projects, often with --dangerously-skip-permissions to vibe code whatever idea is on my mind. Professionally, part of my team builds the AI-IDE rules and tooling for our engineering team that consumes several billion tokens per month just for codegen.

One of the most impactful things we’ve worked on in TypeScript 5.0 isn’t a feature, a bug fix, or a data structure optimization. Instead, it’s an infrastructure change. In TypeScript 5.0, we restructured our entire codebase to use ECMAScript modules, and switched to a newer emit target. What to Know Now, before we dive in, we want to set expectations. It’s good to know what this does and doesn’t m

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
On Sunday March 6, we migrated Stripe’s largest JavaScript codebase (powering the Stripe Dashboard) from Flow to TypeScript. In a single pull request, we converted more than 3.7 million lines of code. The next day, hundreds of engineers came in to start writing TypeScript for their projects. Seriously unreal. I remember a short time ago laughing at the idea of typescript ever landing at Stripe, an

6 Weeks of Claude Code
It is wild to think that it has been only a handful of weeks. Claude Code has considerably changed my relationship to writing and maintaining code at scale. I still write code at the same level of quality, but I feel like I have a new freedom of expression which is hard to fully articulate. Claude Code has decoupled myself from writing every line of code, I still consider myself fully responsible
