TypeScript for C++ programmers
summary
Compares C++ expectations to concrete TypeScript behavior: shows installing with npm install --save-dev typescript, initializing and compiling with npx tsc and tsconfig, and running output with node; demonstrates the classic JavaScript this vs arrow-function bug and that TypeScript still emits JavaScript even when compile errors exist (surprising). Explains structural typing, generics, utility types, const vs readonly semantics, and using .d.ts declaration files and the DefinitelyTyped ecosystem to give type-safe bindings to existing JS libraries.
