Answer
Global installs work everywhere; local installs stay inside a project folder.
Quick Answer
Global installation (npm install -g) installs the package for use as a CLI command anywhere on your machine — like installing nodemon globally. Local installation (npm install) installs into node_modules in the current project. For libraries you import in code, always install locally — global packages aren't part of your project's dependency tree.
