Writing a template in one go, all in one file, is still vastly easier to wrap your head around than writing all sorts of different components in JavaScript and then gluing them together. There's great JS templating frameworks, but I don't see why anyone would use them unless you really have to, e.g. for data binding / dynamic changes to the DOM.
