In this episode, we are joined by special guest Josh Goldberg to teach us about getting started with TypeScript from scratch. If you're new to TS, this is a great introduction! And if you've been using TS for a long time, you can explain to your friends where they should start to make their experience smoother. In the news, Nx gets support for project references and we curate some of the best TSGo content.
