Why are there .js files in the project?

As per T3-Axiom #3, we take typesafety as a first class citizen. Unfortunately, not all frameworks and plugins support TypeScript which means some of the configuration files have to be .js files.

We try to emphasize that these files are javascript for a reason, by explicitly declaring its type (cjs or mjs) depending on what’s supported by the library it is used by. Also, all the js files in this project are still typechecked using a @ts-check comment at the top.
