Pug is wonderful, and this project is aimed at programmers since you need to know your way around Vue.js if you want to make anything with it. From their docs: "If you are not familiar with Vue.js you will find eagle.js harder to use than, say, Reveal.js, but on the long term eagle.js makes it easier to organize your slides and implement new ideas." In any case Pug is really easier on the eyes as it's a lot less code to read/parse.
