There are a lot of options to choose from when it comes to templating engines. Same of the most popular ones include Pug(Jade), Handlebars, Mustache, Nunjucks, EJS, Dust, etc..
So far I've tried just Pug and EJS and I must say I prefer EJS without a doubt. Each one is not that hard to learn, so it's worth investigating each one.
Which ones have you tried and which one did you settle on?
