Difference Between Package.json and package-lock.json

Can anyone elaborate the difference between package.json and package-lock.json? I was following Andrew Chalkley on npm basics course. He deletes the node_modules folder and use npm install to regenerate it. After that, there are only 3 folders inside his node_modules folders which is bcrypt, nan and colors. But when I did it, it installed a huge bunch of other stuff into my node_modules folder. But i have only 2 dependencies inside my package.json file and when I do "npm install" it automatically generates another JSON file which has so many dependencies. Why is that?
