TSConf 2020 Talk: A Trip into the Compiler

TSConf 2020 Talk: A Trip into the Compiler

The TypeScript compiler is a complex piece of software. What is it like to work on the TypeScript compiler? You’ll learn about how the compiler is structured and the process of implementing a large feature in the compiler, based on my experience contributing to the ES private fields implementation that shipped in TypeScript 3.8. Along the way, you’ll also gain familiarity with ES private fields, how they interact with existing TypeScript features, and what they mean for TypeScript developers. After this talk, hacking around in the compiler codebase hopefully won’t feel so daunting!
