@ntedgi - thanks!

Can I propose you to have a look at https://nodejs.org/dist/latest-v15.x/docs/api/buffer.html#buffer_static_method_buffer_isbuffer_obj and see if you can add an example code (that is missing there) , following how it is done in the neighboring APIs? the doc for the APIs are in /doc/api/buffer.md . (We want to make sure your intent of contributing to Node.js is achieved!)

closing in favor of #36206
