TypeScript in 50 Lessons

Many developers have heard of TypeScript without grasping what it offers or how to put it to practical use. Written for front-end developers who already work comfortably with JavaScript, this guide walks through the language in fifty short lessons. Each lesson tackles one piece at a time, so the more puzzling aspects of TypeScript become easier to follow.

Stefan Baumgartner lays out the material in a deliberate sequence, starting from the reasons TypeScript exists and moving toward using it in everyday projects. Readers who want a clear path from familiar JavaScript habits to typed code will find the lesson format well suited to steady, hands-on study.
