This is a demo for a StackOverflow question. It will copy the contents of the node_modules folder into a copy folder, using NodeJS.
It copies the folder recursively (meaning that all subfolders will be explored as well), but it does not use function recursion. Instead, it uses a queue, which gets filled by an auxiliary function which we run in a loop.
