package-lock.json

`package-lock.json` is a file used in JavaScript projects that manage dependencies, which are external libraries or packages the project relies on. When you install a package, this file records the exact versions of that package and all its dependencies. This ensures that everyone working on the project, and any future installations, use the same versions, avoiding unexpected issues. In essence, it locks the project's environment, making it more reliable and consistent across different setups, similar to a recipe that specifies every ingredient and amount for a dish, ensuring the same results every time it's made.
