What are the differences between lock files and manifest files?

Lock files and manifest files serve different purposes in package management. A manifest file lists the packages and their versions needed for a project, while a lock file records the exact versions of those packages that were installed, ensuring consistency across environments.

Can you give me an example of each?

Sure! A manifest file might be package.json in a Node.js project, which specifies dependencies. A lock file example is package-lock.json, which locks the exact versions of those dependencies.

Why is it important to have a lock file?

A lock file is crucial because it ensures that everyone working on the project uses the same versions of dependencies, preventing issues that can arise from version discrepancies.

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

Without a lock file, different developers might install different versions of dependencies, leading to bugs and inconsistencies in the application.
