How do I update my package.json file?

You can update your package.json file by manually editing it or using npm commands. What do you want to change?

I want to update the version number and add a new dependency.

To update the version, change the "version" field in package.json. To add a dependency, use npm install <package-name> --save.

Can you show me an example of how to add a dependency?

Sure! If you want to add 'express', you would run npm install express --save. This will update your package.json.

What if I want to remove a dependency?

You can remove a dependency by running npm uninstall <package-name> --save, which will also update your package.json.
