React is more functional favored. It's very recommended for functional languages having static type systems, at least for language like JavaScript heavily relies on object literal.

The problem is, dynamic OOP languages like Ruby and Python are Okay to work with, since you know the class of an object you know a lot of things (schema, behavior, etc).

But for JavaScript and React, mutable classes are not quite useful since they mutate themselves, and could stop the app from re-rendering. it's more likely people are using object literals, which can hardly go far.

With TypeScript's structural and gradual type system, it's flexible and easy enough to type object literals with the union and intersection types, without forcing people to use classes.
