TypeScript 7.0 vs TypeScript 6.0 speed test

TypeScript 7.0 Beta is here — and Microsoft says it is up to 10x faster than TypeScript 6.0.
In this video, I test that claim with real benchmarks by running the same TypeScript code through both compilers: the classic TypeScript compiler and the new Go-based compiler in TypeScript 7.0 Beta.

First, I test a small code sample and compare execution time as well as CPU usage. Then I move on to a much larger project with 5,500 files to see how both compilers perform under real pressure. The results are surprising — and the performance difference gets even more interesting as the workload grows.

Along with speed improvements, TypeScript 7.0 Beta also brings some important changes, including stricter defaults, removed older options, and a cleaner setup for modern projects. I also discuss what these changes mean for developers and whether Microsoft’s performance claims really hold up in practice.

If you are curious about the future of TypeScript, this video breaks down the latest beta update, the speed test results, and the major changes you should know before using it in your projects.
