‘Beacons are parts of a program that help a programmer understand what the code does. You can think of a beacon like a line of code, or even part of a line of code, that your eye falls on which makes you think, "Aha, now I see."
Beacons typically indicate that a piece of code contains certain data structures, algorithms, or approaches.’
Turns out that all that time I spend “making the code pretty” I was just making it understandable. The question is if what I consider pretty/understandable is the same as other programmers would call pretty/understandable
