Exploring the idiomatic approach to object initialization in Go and understanding why we use constructor functions to create new struct instances.

Defer's evaluation timing and named return values that get mutated after the return statement: two Go function features with no real TypeScript equivalent.

A method is just a function with a receiver, a nil interface panics differently than a nil pointer, and iota isn't a TypeScript enum — three Go idioms I had to unlearn my TS assumptions for.

Slice headers, nil comparisons, and pointer fields for optional values: three places Go's syntax looks like TypeScript but the semantics don't match.

Six Go patterns that compile cleanly and quietly do the wrong thing: loop capture, typed nil, slice aliasing, shadowed err, defer in a loop, and range copies.
