In section 6.4.2, the code sets up a "getDraggedFile". This function errors when used in Listing 6.19 because "files" is an empty list, but you can access the file's type via "items". I'd suggest using something like the following:

const getDraggedFile = (event) => event.dataTransfer.items[0];

const getDroppedFile = (event) => event.dataTransfer.files[0];

Then use the appropriate function in the listings that follow.
