I don't know how you work on cross-platform ASP.NET for this long and still not have the tooling for your templating engine ported.

To get as good of a development experience as React, it would require some work by the compiler and runtime people to basically let you do something like hot loading--Android has something like this now, and maybe Apple will get it too, though I'm not holding my breath.

I think it's a no-brainer for web development these days to do React because 1. you can opt out of it for parts of the page it's not going to work with for whatever reason and 2. the performance is pretty damn good compared to lots of alternatives, including writing all the UI state management logic yourself. However, I've not been convinced that the buy-in is worth it for native mobile development. Can someone who knows more tell me: is it fairly easy to do something like say "I can't/don't want to use React Native for this view controller--I'm going to implement it in code and use it and everything will just work."

I haven't written any higher order components myself, unless you consider parameterizing event handlers in props to be higher order.

I also am strongly against string references to model properties in your template. Again, it's much better to use tools that provide some static validation of what you're doing.

Give me React with TypeScript to help me make sure I'm passing around what I said I'm expecting to receive at each point as features are changed and added, and I'll be in business.

Honestly, I use React in spite of my opinion of Facebook.
