This is where I keep small Go case studies that support the technical writing on this site. Each topic is built as a runnable example with tests or benchmarks, so the discussion can point to code instead of relying only on explanation.

Public repo: [github.com/VVivid/vvivid-workspace/tree/main/examples/go-lang-case-study](https://github.com/VVivid/vvivid-workspace/tree/main/examples/go-lang-case-study).

The first case study compares normal string concatenation with `strings.Builder`, including benchmark output and allocation counts.
