Removing local packages

To completely remove unneeded packages from a project, you can use the npm uninstall command:

$ npm uninstall package ...

Where package ... is a list of package names.

When executed, it will:

1. Remove the package from the node_modules directory.

2. Remove the package from the dependencies, devDependencies, and peerDependencies objects of the package.json file.

3. Update the package-lock.json file to reflect those changes in the dependency tree of the project.

Removing global packages

To uninstall a global package, you can use the npm uninstall command with the -g flag.
