使用TypeScript的数组项中的接口唯一值

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

const people: Person[] = [
  { id: 1, name: "Alice" },
  { id: 2, name: "Bob" },
  { id: 3, name: "Charlie" }
];

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

function ensureUniqueById(people: Person[]): Person[] {
  const uniquePeople = [];
  const idSet = new Set<number>();

  for (const person of people) {
    if (!idSet.has(person.id)) {
      uniquePeople.push(person);
      idSet.add(person.id);
    }
  }

  return uniquePeople;
}

const people: Person[] = [
  { id: 1, name: "Alice" },
  { id: 2, name: "Bob" },
  { id: 3, name: "Charlie" },
  { id: 1, name: "Alice Duplicate" } // 重复的ID
];

const uniquePeople = ensureUniqueById(people);
console.log(uniquePeople);

[
  { id: 1, name: "Alice" },
  { id: 2, name: "Bob" },
  { id: 3, name: "Charlie" }
]
