如何使用Javascript为每个对象动态分配ID

let idCounter = 0;

function createObject() {
  const newObject = {
    id: idCounter++,
    name: `Object-${idCounter}`
  };
  return newObject;
}

const obj1 = createObject();
const obj2 = createObject();
const obj3 = createObject();

console.log(obj1); // { id: 0, name: 'Object-1' }
console.log(obj2); // { id: 1, name: 'Object-2' }
console.log(obj3); // { id: 2, name: 'Object-3' }

function generateUniqueId() {
  return '_' + Math.random().toString(36).substr(2, 9);
}

function createObject() {
  const newObject = {
    id: generateUniqueId(),
    name: `Object-${generateUniqueId()}`
  };
  return newObject;
}

const usedIds = new Set();

function generateUniqueId() {
  let newId;
  do {
    newId = '_' + Math.random().toString(36).substr(2, 9);
  } while (usedIds.has(newId));
  usedIds.add(newId);
  return newId;
}
