• Flow Language Support

You might wonder if this is really necessary.
Well, Here is why I came to think it is - Expect the type of Get Posts API.

I was building a Mattermost integration and I expected it would of course be an array of Post.
And I had to see the result ofmap is not a function because of the result of the Get Posts API that looks like:

{"order": ["post_id1","post_id2"  ],"posts": {"post1": {},"post2": {}  }}

• It was your fault. Mattermost have documentation for it.
• Why did you not write test, evil.

You can think it is wrong not to check the documentation or write test code. But generally it could be skip when productivity is important like in prototyping.type checking is simple and a great solution to avoid mistakes.

• PropTypes is not enough?

PropTypes is great sollution to assert types. But it's only for React component.
