When actively scraping, the main starting function is
document.querySelectorAll()
This will return a NodeList, which typically one will use a for-loop to loop over each item.
On each item either the querySelector or querySelectorAll will be applied recursively until all specific data instances are extracted.
This data is then saved into various formats depending on future processing, either as on object in an array or as a string, which is then saved either to the localStorage, sessionStorage, IndexDB, or downloaded via a temporal link.
