在typescript中，有没有一种方法可以访问类型数组的接口属性？

interface Person {
  name: string;
  age: number;
}

const people: Person[] = [
  { name: 'Alice', age: 20 },
  { name: 'Bob', age: 25 },
];

type PersonKey = keyof Person[]; // "length" | "push" | "pop" | ...

interface Person {
  name: string;
  age: number;
}

type PartialPersonArray = Array<Partial<Person>>; // 将每个属性变为可选
type ReadonlyPersonArray = ReadonlyArray<Person>; // 将数组变为只读

const partialPeople: PartialPersonArray = [
  { name: 'Alice' },
  { age: 25 },
];

const readonlyPeople: ReadonlyPersonArray = [
  { name: 'Bob', age: 30 },
];
