It's not just you...this has been a pretty big toss-up with MVC style frameworks and view libs. Does business logic belong in the template? Or does it belong in some sort of view controller? Mustache.js insists that all decisions should be made before data is sent to the template. Most other libs allow the template to make decisions. I don't think there's a definitive answer. I kinda lean on making easy decisions in Handlebars templates... or, since our new app is in React, JSX.
