I like the way redux divide the code into actions and reducer. In my opinion the application code is clear with redux.

Off the topic, I mainly write in Python. I started programming in C/C++. I very often miss header files from C/C++ during Python programming. In C++ header files you have the full interface definition and it was easy to understand the code. Somehow, the redux and C header files are for me similar (in the sense of clear code).
