Symphony itself brought quite a few concepts from Rails to the PHP community. You can call the flow of ideas across communities "reinvention" but I think it's super healthy. The web platform has had been an oddity in asking you to entirely switch languages when moving between backend development and frontend development. I think one of the most appealing pieces of these Javascript frameworks is that you can build everything in one common language. (You can—but don't have to.) Fine-grained developer control of when data is fetched, when components are rendered, how they are rendered, and where they are rendered (server vs client) becomes a really welcome advancement.
