What's TypeScript?

• An open-source typed, syntactic superset of JavaScript, developed by Microsoft
• Compiles to readable JavaScript
•  Comes in three parts: Language, Language Server and Compiler

Why?

•  Encode constraints and assumptions, as part of developer intent
•  Catch common mistakes (i.e. incomplete refactors)
•  Move some runtime errors to compile time
•  Provide your consumers (including you) with a great DX
