This is the perfect lecture when you need quick results. However, there are many missing explanations here and there. I had to study the methods used in the lecture myself to understand them. However, I think it was better because I studied by looking them up myself rather than having them tell me everything. To summarize Pros: It is good for beginners in pure vanilla JS to build a foundation. Quick completion of portfolio results Cons: Lack of explanations here and there, small text makes it hard to see..., slow feedback on questions. Overall, it was a pity that feedback on questions was not provided quickly, but since the price is cheap, I think there is no other lecture with this much cost-effectiveness. Since it proceeds with pure vanilla JS code, I recommend it to beginners in JavaScript.
