When it comes to managing dependencies in Node.js projects, understanding the difference between package.json and package-lock.json is crucial. Package.json defines project metadata, dependencies, version ranges, and scripts, while package-lock.json ensures consistency across environments by locking down exact versions of dependencies.

Package.json is manually created or auto-generated when initializing a project using npm init, providing key details that help both npm and developers manage the project. Package-lock.json, on the other hand, is automatically generated when installing or updating dependencies using npm, ensuring that everyone working on the project installs the same dependency versions.

Both files play critical roles in maintaining project stability and consistency, making it best practice to commit them to version control. By understanding the differences between package.json and package-lock.json, developers can effectively manage their projects and ensure smooth collaboration across environments.
