Joshua Chen

Specialist in JavaScript and related technologies. Maintainer of the MDN JavaScript documentation. Contributor to impactful JavaScript infrastructure projects such as TypeScript and typescript-eslint. My main work focus is compilers and static analysis, but I am also interested in computation models and functional programming.

My Yale undergraduate study is mostly around quantitative social science, with a curriculum focused on statistics, data science, and the syntax and semantics of natural languages.
