I didn't say polymer can't do it. What I'm saying is that certain constructs are more difficult to write in polymer. Or involve more code and indirection. Most apps will have their core data loaded into nice JavaScript objects and class instances. With react the transformation of that data into DOM is a one step process. With polymer you have to first map that data to javascript primitives which are consumed by expressions which then generate the DOM. I guess ultimately it's my preference to having types (I use TypeScript) which can be used inside the rendering code to ensure correctness. With polymer you lose some of that because everything ends up in these untyped expressions.
