Note: Angular and React are vastly different frameworks (react calls itself a library) and comparing them straight up is comparing apples to oranges. Same goes for ember and reactThat said, I use and love React. I'm not saying there is anything wrong with any of the frameworks mentioned. AKA HackerNews please don't kill me.
Watch the videos below and take away from them what you will.
Let me know if you have any other links/resources for comparisons in the comments below.
