Type Assertions, Type Switches, and Interface Internals

How Go recovers a concrete type from an interface value, why the comma-ok form exists, and the two-word memory layout that explains the single most surprising bug in the language — the non-nil interface holding a nil pointer.

Methods and Receivers

How Go attaches behavior to types without classes — the receiver, the value-versus-pointer decision, method sets and what they mean for interfaces, and the addressability rules that trip people up when a value lives in a map.
