Description

A working programmer's guide to TypeScript that skips the tour of syntax and starts where the difficulty actually is: modelling a domain so invalid states cannot be represented, and getting useful errors instead of cryptic ones. Chapters cover discriminated unions, generics that stay readable, narrowing, declaration files, and the compiler options worth changing on an existing project. The final third is a set of migration case studies — a JavaScript codebase moved incrementally, with the diffs and the decisions behind them.

Changelog

2nd edition (2026-05-08) - New chapter on declaration files - Examples updated to TypeScript 5.6 - Added two migration case studies
