检查数组中是否包含特定顺序的特定项

function containsSpecificOrder(arr, specificItems) {
  let currentIndex = 0;
  
  for (let i = 0; i < arr.length; i++) {
    if (arr[i] === specificItems[currentIndex]) {
      currentIndex++;
      
      if (currentIndex === specificItems.length) {
        return true;
      }
    }
  }
  
  return false;
}

// 示例用法
const array = [1, 2, 3, 4, 5];
const specificItems = [2, 3, 4];

console.log(containsSpecificOrder(array, specificItems)); // 输出 true
