Is ReasonML production ready?

This is a bit of a silly question I'm my opinion, because it's a little vauge what it actually means.

Basically they are saying:

  1. Do other big companies invest in it enough to ensure that it's never going to just become unsupported
  2. Has it got enough libraries so that I don't have to invest very much to do my daily tasks reinventing the wheel? Are these libraries got stable and active maintainers?
  3. How many gotchas and rough edges does it have? Will I run into issues that I can't solve easily?
  4. Can I be more productive than JavaScript?
  5. Has the syntax and best practices been estblished?

Ok that's a lot of questions, let's try to answer them in turn.

The real question is are you ready to use Reason in production. Remember there's always a trade-off of innovation and stability. Stability only comes from people using it a lot. Admittedly a language as strict as ReasonML is going to more quickly find issues so long as they aren't using more risky features like binding to JavaScript.
