He lost me at the moment he showed me the all-encompassing, all-powerful, all-knowing spaghetti wrapper function in JS. If he really wanted to build a nice looking web template solely with front end technologies, he could build it with Jade for the HTML part, Sass for the CSS, and JS/TS/Babel for the behavior part and structure the template in a modular and component-based fashion for reusability, maintainability, scalability, customizability, and above all sanity. If you're looking to build a web app instead, just pick any framework you feel comfortable and your future self will thank you for that decision as the web gets bigger and bigger, you'd still can keep it together and deliver good results consistently.
