I seen some tutorials on Youtube but they don't talk how they think to do that and their content is general content and not deep and clearly why they do that. Recently I find your channel. Your channel is so good, you give clearly content especially easy understand about React JS that I am watching that make me learn React JS and the others more fast. Thank you and appreciate your support
