以顺序和结构化的方式合并两个数组

function mergeArrays(arr1, arr2) {
  var mergedArray = [];
  
  for (var i = 0; i < arr1.length; i++) {
    mergedArray.push(arr1[i]);
  }
  
  for (var j = 0; j < arr2.length; j++) {
    mergedArray.push(arr2[j]);
  }
  
  return mergedArray;
}

var array1 = [1, 2, 3];
var array2 = [4, 5, 6];
var merged = mergeArrays(array1, array2);
console.log(merged); // 输出 [1, 2, 3, 4, 5, 6]

exports.main_handler = async (event, context, callback) => {
  var arr1 = event.array1;
  var arr2 = event.array2;
  var mergedArray = [];
  
  for (var i = 0; i < arr1.length; i++) {
    mergedArray.push(arr1[i]);
  }
  
  for (var j = 0; j < arr2.length; j++) {
    mergedArray.push(arr2[j]);
  }
  
  return mergedArray;
};
