About this course
Starting from a finished job application tracker and the command line tool that reads its log, you turn eighty-five files into strict TypeScript, one at a time, and learn the language from what each conversion demands. Inference, unions, narrowing, generics, discriminated unions, declaration files, the DOM and its nulls, a typed Node server, and the migration playbook for the codebase you have at work.
