Question 5

What happens when you add a dependency to a package with npm?

Answer 5

The package specified in the npm install command is downloaded from the npm registry and installed in the node_modules directory of your project.

The package and its dependencies (if any) are added to the dependencies field of your package.json file.

If the package has its own dependencies, those dependencies are also downloaded and installed in the node_modules directory, and added to the dependencies field of your package.json file.

The installed package can now be imported and used in your codebase.

When you run npm install command again, npm checks the dependencies field of your package.json and installs any missing packages. It also ensures that the installed versions of the packages match the versions specified in the dependencies field.
