TypeScript is a statically typed superset of JavaScript that adds optional type annotations and modern language features to improve developer productivity and code safety. The TypeScript compiler performs type checking at compile time, catching errors before code is run, and also transforms TypeScript code into clean, standards-compliant JavaScript.
Jake Bailey is Senior Software Engineer at Microsoft where he works on TypeScript, and has made major contributions to the TypeScript compiler. Jake joins the podcast with Josh Goldberg to talk about TypeScript and his work.

Josh Goldberg is an independent full time open source developer in the TypeScript ecosystem. He works on projects that help developers write better TypeScript more easily, most notably on typescript-eslint: the tooling that enables ESLint and Prettier to run on TypeScript code. Josh regularly contributes to open source projects in the ecosystem such as ESLint and TypeScript. Josh is a Microsoft MVP for developer technologies and the author of the acclaimed Learning TypeScript (O’Reilly), a cherished resource for any developer seeking to learn TypeScript without any prior experience outside of JavaScript. Josh regularly presents talks and workshops at bootcamps, conferences, and meetups to share knowledge on TypeScript, static analysis, open source, and general frontend and web development.
