I have to admit this is the first time I've heard about Reason. Could you help me understand the reason for it?

Is this because Microsoft has TypeScript, Apple has Swift, and so now Facebook has Reason to keep all your application in your more/less proprietary format?

Further, if you already have React, then why not write everything in React and then just extend it with the features you've built into Reason?

Pardon if these aren't clever questions, but I'd love to understand the big selling points here. Thanks!
