如何检查类的数组？

class MyClass {
  constructor(value) {
    this.value = value;
  }
}

const array = [new MyClass(1), new MyClass(2), new MyClass(3)];

function isArrayOfClass(arr, className) {
  return arr.every(item => item instanceof className);
}

console.log(isArrayOfClass(array, MyClass)); // 输出: true

function isArrayOfClass(arr, className) {
  return arr.every(item => item.constructor === className);
}

console.log(isArrayOfClass(array, MyClass)); // 输出: true

function isArrayNotOfClass(arr, className) {
  return !arr.some(item => !(item instanceof className));
}

console.log(isArrayNotOfClass(array, MyClass)); // 输出: false

function validateArray(arr, className) {
  if (!isArrayOfClass(arr, className)) {
    throw new Error('Array contains invalid instances');
  }
}

try {
  validateArray(array, MyClass);
  console.log('Array is valid');
} catch (error) {
  console.error(error.message);
}

function optimizedIsArrayOfClass(arr, className) {
  const prototype = className.prototype;
  return arr.every(item => item.__proto__ === prototype);
}
