Total TypeScript

Bring a recurring type problem to the training rather than memorizing fixes in isolation. The introduction emphasizes mental models for errors, generics and use of any. That makes its scope relevant when you already write JavaScript but want to reason more deliberately about a typed codebase. The paid workshop bundles are self-paced and aimed at advanced beginners through experts. They include interactive exercises, video, transcripts and progress tracking; the site also provides free tutorials.
