Testing
Pick the IDIOMATIC failure-reporting line inside a Go
test function. (got and want are local variables;
t is the *testing.T.)
TypeScript: expect(got).toBe(want). Go has no
assertion library — testing.T's methods + a bare if
are the whole vocabulary.

About this theme
Go has a testing package in the standard library. Tests live next to code in _test.go files. The pattern is table-driven: a slice of (name, input, want) tuples plus t.Run(name, ...) for subtests. No assertion library required — if got != want { t.Errorf(...) } is the whole vocabulary.
