In Exercism v3, each track must specify exactly six "key features". Exercism uses these features to highlight the most interesting, unique or "best" features of a language to a student.
Key features are specified in the top-level "key_features" field in the track's config.json file and are defined as an array of objects, as specified in the spec.
