VS Code and TypeScript practically grew up together. We made a bet early on to write VS Code in TypeScript, and we have always worked closely with the TypeScript team to provide great built-in TypeScript and JavaScript language support in VS Code. This post is about the next step of that journey: TypeScript 7, and how collaborating on adopting TypeScript 7 sped up our builds, improved the day-to-day editing loop for both developers and agents, and helped the TypeScript team ship a more tested release.
