The JSDoc snippets are certainly outdated (the TODO was introduced almost 12 years ago in cec0c06). Most recent change to existing lines is fce3d14 (#2663) from 10 years ago. In the meantime, the documentation on the website (repo) has received some improvements and fixes - most importantly expressjs/expressjs.com#1147 and expressjs/expressjs.com#504, but also expressjs/expressjs.com#324 which reworded the description.

I'd suggest porting the changes made to the API docs on expressjs.com - especially the return types. I wouldn't be surprised if there is more outdated JSDoc documentation, but I don't have time to check that.

@krzysdz So sounds like a good opportunity for a first PR.
Taking this :)
