I was in awe of how much demand React Dev skill is to the marketplace and I'm glad you put up a course this in-depth.

    You simplified the complex concepts so much so that they appear to be easy. I am sure a lot of effort went into doing that. Really appreciate your work. Your style of teaching is amazing. Every sentence that you speak is well thought of and crystal clear. Not a moment comes in any of your videos that one would need to scratch his head to think what you are doing in the code in that moment. You always clearly state in each line of your code what we are trying to achieve. I want to truly thank you from the bottom of my heart. Keep up the amazing work and keep inspiring us to continuously learn :)

    I'm about to watch the last video of this React Redux Tutorial and I just want to say that you're a great teacher. You calm demeanor and how you walk the learner through everything with visual cues (highlighting text, pointing with the mouse, scrolling to the sections as you explain) is very helpful. Some may take it for granted but it helped and reassured me as you summarized the material towards the end of each of your videos.
    All the best you Vishwas in your future endeavors. Take care and thank you very much🙌

    7)How do you share logic across components?

    Redux:
    What is Redux?
    How do you decide whether to use contextApi or Redux?
    What is the redux store?
    What are actions?
    What are action creators?
    What are reducers?
    How control flows between these parts?
    What exactly does the connect function do from the react-redux library?
    What do mapStateToProps and mapDispatchToProps actually do?
    Why should you dispatch an action to update a state and not update the store directly.
    In a reducer, why should you return a new object as state instead of modifying the existing state object?

    When I'm asked about what I like/dislike about a certain library/framework, I always give the same answer: nothing, since these are just freakin' tools to get the job done. I don't have to be emotionally attached to any of them. Whether I use React or Angular or Vue or even just vanilla JS it makes no real difference as long it serves its purpose in a given project.
