Frontend Libraries React/Redux course

I started learning React from freecodecamp’s React challenges, and the material is good enough to quickly learn the main concepts even though I feel that it misses more challenges about Life-Cycle event.

Anyhow my main point of writing this post starts from Redux Store.
which is not clear and full of confusion, I feel that Redux challenges are not easy for beginners to understand the concepts. As you know this is beta so not easy to find solutions to the challenges.

I am struck by challenge 6 - Redux: Handle an Action in the Store

I request you guys to make it simple for the first few challenges to understand the concepts and later make it hard when we are getting deeper.
