>there are way too many options parading around as serious contenders. Its early days for some of these concepts on the web (I mean, discounting some stuff that happened years ago at Xerox Parc which got beat out by worse technology). So by what objective measure are there too many options? There are a few very well established options: React, Angular, and Ember. If you need standards and heavyweight support and reliability, use one of those things. I'm sure in a few years, things will have coalesced and standardized a bit further.
