Are there any good tools for simplifying / getting rid of unnecessary syntax is html? Is jade the best?
Afaik Pug (Jade) is the most-used backend templating language outside of EJS (which ships as default with Express, and just looks like HTML + some templating tags). Slim is very similar to Pug. There are a few others, but it’s much of a muchness: they all have a quite limited usecase, there’s not really a ‘best’. pug/slim/haml style templating languages don’t simplify, they just reduce the verbosity, so you just move the complexity somewhere else.
