Go into this with prior knowledge of why things work.
Mosh as a teacher is very good, he tells you how to do something and you feel like you are doing it yourself. As a learner, you have a very good time with learning from Mosh because he explains topics very well. My only issue is that he does not go into detail when teaching certain topics, so you're left with the knowledge of how to write code, but you don't have a full grasp on why the code works the way it does. Which makes me feel like I'm being handed a toolbox to build something and not being told what any of the tools do, just what they are. Overall, the way Mosh explains certain topics is great, I think it's very simple to understand and his courses offer a lot more than what you would find anywhere else online for free. My only problem is you have to have prior knowledge of certain things, and you have to go out of your way mid-lecture to research why what you just learned works the way it does, when it should be used and when it shouldn't. Code with Mosh courses are very good and informative, you are taught to program by someone who clearly knows what he's doing and it will leave you satisfied after you finish a course and feel like you've truly learned a lot. But you have to know the basics of why things work the way they do if you want to actually apply the knowledge you've gained from this course to the real world, you have to do some research. I think the experience is great and Mosh is a great teacher, I just wish there was more explanation and examples for whenever something new comes up.
