TypeScript 7 and What Comes Next

TypeScript is a programming language that builds on JavaScript by adding a system of types. Those types let developers describe the shape of their data and catch mistakes before code ever runs, while also powering the auto completion and editor tooling that many developers now rely on every day. It was first released in 2012 and has since become one of the most widely used tools in web development. TypeScript recently underwent one of the most significant changes in its history with the release of version seven. Daniel Rosenwasser is the principal product manager of TypeScript at Microsoft, where he began as an engineer on the team just weeks after the TypeScript one point o release. In this episode, Daniel joins Josh Goldberg to talk about the features of TypeScript seven. They discuss the TypeScript team's approach to tooling, TypeScript's relationship with the TC 39 standards process behind JavaScript, the new API and IPC boundary, how LLMs could reshape type checking and linting, and more. This episode is hosted by Josh Goldberg, an independent full time open source developer. Josh works on projects in the TypeScript ecosystem, most notably TypeScript ESLint, a powerful static analysis toolset for JavaScript and TypeScript. He is also the author of the O'Reilly Learning TypeScript book, a Microsoft MVP for developer technologies, and a cofounder of SquiggleComp, a conference for excellent web developer tooling.

Thank you so much for having me. Great to talk to you today, Josh. Yeah. We're really excited to have you. I've been looking forward to this. There's a lot of cool stuff happening in TypeScript, both with the recent releases and then upcoming upcoming work. But before we dive into that wonderful world, Daniel, how did you get into tech? How did you get into tech? Oh, I feel like this is a very common one for a lot of people, you know, video games, things like that. And then getting a little bit more and more and more curious about all the sorts of things and how they work and thinking, oh, maybe I could do this or that. But I think the funny thing was, for me with well, I I mean, maybe programming specifically, the way I got into a lot of that was through just maybe the earliness of the Internet and then just meeting random people on forums and probably being a little bit too young to be on, like, a video game forum at the time. Right? Like, I don't know. Maybe 10, 11 years old or something like that. But meeting these random people from around the world and then finding out that they were, you know, 15, 16, 17 years old and running a forum themselves and and realizing, like, hold on a second. You're all a bunch of teenagers running a website, and …
