打字稿在这种情况下如何重用打字稿？

Question

interface Test {
  name: "abcd" | "efgh" | "ijkl";
}

interface Human {
  name: "abcd" | "efgh" | "ijkl"
}

我想与Human.name一起重用Test.name的类型，但是如何？有什么想法吗？

Answer 1

将名称提取为联合类型

type NameTypes = "abcd" | "efgh" | "ijkl";

interface Test {
  name: NameTypes;
}

interface Human {
  name: NameTypes;
}

Answer 2

这也应该起作用

interface Test {
  name: "abcd" | "efgh" | "ijkl";
}

interface Human extends Test {

}
