It contains the essential content required for Dapp development. It is even better because it is not burdensome. The regrettable thing is that there are parts that change from the point of view of watching the lecture as time passes. For example, the UI of the tools used in the lecture changes, the usage method changes slightly, and the Solidity version is a little low at the current point. Of course, this is something that can be solved with a little search. Thanks to this, I am gaining valuable knowledge easily and quickly. I sincerely thank you.
