The Complete Guide to TypeScript & Modern Static Type Systems
Developed and open-sourced by Microsoft, TypeScript is a strongly typed superset of JavaScript that compiles directly to clean, standard JavaScript. By adding compile-time static type annotations, generic type constructors, strict null checks, and interface contracts, TypeScript drastically reduces production runtime exceptions and powers autocompletion across modern engineering codebases.
