it's really difficult to keep up with all the terminology. A list of terms and their definitions would be extremely helpful.For example, what does heap mean? It's never really explained in detail. I'm only on episode 3 and I'm so lost ā¹ļø. I'm so overwhelmed by the amount of knowledge I'm just expected to know.
