AI translates the explanation and quiz text while preserving code and answer scoring.

Tests live in _test.go files as func TestXxx(t *testing.T). Table-driven tests iterate over cases with t.Run subtests. Benchmarks use *testing.B, and the race detector (`go test -race`) finds concurrency bugs that are otherwise intermittent.

How to study this topic

  1. 1. Read the explanation once end to end, skipping the code.
  2. 2. Re-read the code snippets and say out loud what each line does.
  3. 3. Answer the quiz without scrolling back — that is the real check.
  4. 4. Read every explanation, even for the answers you got right.
