Study Notes
TypeScript is a free and open-source programming language developed by Microsoft that adds static typing with optional type annotations to JavaScript. TypeScript supports definition files that can contain type information of existing JavaScript libraries.

TypeScript may be used to develop JavaScript applications for both client-side and server-side execution. The TypeScript compiler is itself written in TypeScript and compiled to JavaScript. TypeScript was released to the public in October 2012, with version 0.8, after two years of internal development at Microsoft. TypeScript 5.0 was released on 16 March 2023.
