从类型的属性中生成的字符串数组| Typescript

type MyType = {
  name: string;
  age: number;
  gender: string;
};

function getPropertyNames<T>(obj: T): string[] {
  return Object.keys(obj) as Array<keyof T>;
}

function generateStringArrayFromTypeProperties<T>(obj: T): string[] {
  const propertyNames = getPropertyNames(obj);
  return propertyNames.map((propertyName) => String(propertyName));
}

const myObj: MyType = {
  name: "John",
  age: 25,
  gender: "Male",
};

const stringArray = generateStringArrayFromTypeProperties(myObj);
console.log(stringArray); // Output: ["name", "age", "gender"]
