🥶 Announcing TypeScript 5.9 One of TypeScript's gentlest steps forward, with support for import defer, --module node20, and ‘expandable hovers’ (below) to see expanded type information in IDEs. We also learn v6.0 will act as a ‘transition point’ to get prepared for the Go-powered ‘native port’ of TypeScript due to arrive as TypeScript 7.0. Microsoft
