The article didn't touch on this very well, but the reason to upgrade from cheerio to jsdom is if you want to run scripts. E.g., for client-rendered apps, or apps that pull their data from XHR. Since jsdom implements the script element, and the XHR API, and a bunch of other APIs that pages might use, it can get a lot further in the page lifecycle than just "parse the bytes from the server into an initial DOM tree".

(I'm a maintainer of jsdom.)

Running the [arbitrary] scripts not written by me is what I usually try to avoid and fear when scraping.
