superset languageとかどうでしょう?erniogi.icon
たしかに!TypeScriptの文脈ではsupersetと言いますねmrsekut.icon
具体例が増えてきたので、そのうち著名な人が一括にした名詞が登場しそう
However, TypeScript is a typed superset, meaning that it adds rules about how different kinds of values can be used. The earlier error about obj.heigth was not a syntax error: it is an error of using some kind of value (a type) in an incorrect way.
