jsduck is no longer maintained. As we're using it.. We should probably try and decide what to do next, as we need to make some changes to it to fix up things like T213282: JSDuck at doc.wikimedia.org loads fonts from google... Find something else? Take over maintainership? Fork it? Something else?
Yup, the plan for a couple of years now has been to migrate to jsdoc. See T138401: Replace jsduck with JSDoc3 across all Wikimedia code bases. Last remaining blocker is getting everyone happy with the design of the custom theme that @Prtksxna has built: T187672.
