title: React Native v Xamarin Forms - Choosing Cross Platform App Environment
body: <p>I have been looking at Xamarin Forms for building a cross platform App. We would like a framework which targets iOS, Android and Windows Phone. It seems like a nice product, but the license cost may cause us a problem with our business model and also licensing for Windows Phone development is unclear.</p>
  
  <p>I have come across another framework called React Native which claims to be able to build cross platform apps.  I wondered if anyone could give me an idea of its strengths and weaknesses, in particular, relative to Xamarin Forms if possible.  One thing is that it uses Javascript, which may not scale well (either in terms of code maintenance or execution performance).  But I would be grateful for input from anyone who has looked closer at React and has formed some objective opinions about its usefulness.</p>
