What is the difference between lock files and package files?

Lock files and package files serve different purposes in dependency management. Package files list the dependencies your project needs, while lock files ensure that the exact versions of those dependencies are installed.

Can you give me an example of each?

Sure! A package file, like package.json in Node.js, specifies the dependencies. A lock file, like package-lock.json, records the exact versions of those dependencies.

Why are lock files important?

Lock files are crucial because they provide consistency across different environments, ensuring that everyone working on the project uses the same dependency versions.

What happens if I don't use a lock file?

Without a lock file, you might encounter issues with dependency versions changing, leading to bugs or inconsistencies in your application.
