# Rustdoc JS | |
These JavaScript files are incorporated into the rustdoc binary at build time, | |
and are minified and written to the filesystem as part of the doc build process. | |
We use the [TypeScript Compiler](https://www.typescriptlang.org/docs/handbook/jsdoc-supported-types.html) | |
dialect of JSDoc to comment our code and annotate params and return types. | |
To run a check: | |
npm i -g typescript | |
tsc --project tsconfig.json |
