It’s a web build tool, which does basically the same thing as every other web build tool — it takes a bunch of developer-friendly inputs (multiple files, typescript, JSX, scss, raw images) and turns them into browser-friendly outputs (single-file, vanilla JS, vanilla CSS, optimised images)
The selling point for parcel is that it does the above with zero configuration (you point it at your input directory and it automatically figures out which compilers / optimisers to use -- other builders typically require hours of googling for / installing / configuring / debugging plugins)
