I know you're trying to be helpful, but I'd like to make clear that if you're a noobie, you don't need any of these tools. Plain Javascript is just fine, especially with the improvements of ES6.
Tools are here to solve problems. Don't bother with them until you have that problem yourself. If you one day decide you want to set up things like auto-minification, image compression, CSS-preprocessing, then look into build script options. Otherwise, it'll just overwhelm you.
