I just realized that in the node_modules folder, there are several .package-lock.json files. What is the use of them? And how are they different from the package-lock.json file in the top level folder?

For the package-lock in your node_modules : Those are the informations such as versions, name, author, dependancies,..etc from the respective libraries you installed in your project.

For the package-lock in your root folder : Same informations but directly related to your project.

So basically every module node_modules is just a node project created by someone just like yours and you're installing it as a dependency so it gets added to your package-lock, so if this someone installed another module to help make theirs (dependency) it will get added to his package-lock
