ReactJS is a no-no from the get go. Facebook's Patent grant on what is supposed to be an "open source product" is ridiculous: https://github.com/facebook/react/blob/master/PATENTS https://github.com/facebook/react/blob/master/PATENTS. "If you ever start a patent conflict with Facebook in court, (worse but even more likely:) or if Facebook starts a patent litigation against you, you LOSE all your rights to use React in ANY product throughout your company and MUST stop using it at once in your code!" Imagine how that can bring a team down. If folks know of anything out there that works like React (I like the ideas, including JSX) but isn't hobbled simply by mis-virtue of being "backed" by the characterless evil that is Facebook, kindly enlighten me, I will use it. I'm actually wondering if the new "open source" Parse code will have the same Patent horror built-in, and if yes that's even worse considering backends can be even more complicated and important part of a company's infra. Also, I'm sure there are people saying "hey, your work may not be significant enough to cause a Patent violation with Facebook so you and the majority of library users are safe". Sure, that is likely true. But it's about the principle.
