Why should I even care about this when there's an abundance of great tools already? npm is baked into your process already. No build tools are needed and any command you run at the command prompt today can be moved into your package.json with one line of code. The Node package library, that you most likely are using anyway, is vast and contains just about anything you need for your automation. Keeping it in npm and package.json means that everyone can use it. No additional configuration is needed. Just npm install and then use the scripts. You now only have one place to keep updated.
