This is a very noob question. I started with React. Its just great. While I was working on the "component" thinking, I just thought react does provides "states" concept in which we can store the component's state. Which is ( for me ) looks like React does provides the model too (what I'm thinking right now is setState as a model and render as view of React lib). Probably my thought process is wrong over here. Am I wrong here?

But if one can store the component state in React setState, why one should look for "Redux" or any Flux libs?
