TypeScript 7 Is Here: What's 10x Faster Today, and What Still Needs Manual Wiring
A few weeks ago I wrote about Anders Hejlsberg — the man who gave us Turbo Pascal, Delphi, C, and then bolted a real type system onto JavaScript with TypeScript — and I noted, almost in passing, that his team had "been rewriting their…
