Microsoft has announced the TypeScript 7.0 Beta, promising developers a true game-changer in terms of performance. The new version, which is reportedly up to ten times faster than TypeScript 6.0, operates much more efficiently in many scenarios as its core components are based on the high-performance Go programming language.
Internally, Microsoft has been working intensively for nearly a year with major tech industry players such as Google, Slack, Figma, Notion, Vercel, and Canva. The release is stable enough for developers to integrate into their daily production workflows, even though it is still a beta version.
Backward compatibility was a central focus of version 7.0: The TypeScript beta can be installed in parallel and behaves like TypeScript 6.0 in terms of both type-checking and command-line operations. However, developers should note that some deprecated features now trigger strict errors—for instance, the target: es5 configuration is no longer supported. Furthermore, predefined settings such as strict: true and module: esnext are now enabled by default.
Developers who want to test the new version directly with their own codebase can do so via the npm package manager (npm install -D @typescript/native-preview@beta) or through a special extension for Visual Studio Code.
