将两个数组合并为一个数组

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

array1 = [1, 2, 3]
array2 = [4, 5, 6]
mergedArray = []
for element in array1:
    mergedArray.append(element)
for element in array2:
    mergedArray.append(element)
print(mergedArray) # 输出 [1, 2, 3, 4, 5, 6]

array1 = [1, 2, 3]
array2 = [4, 5, 6]
mergedArray = array1.copy() # 复制array1的内容
mergedArray.extend(array2) # 将array2的元素添加到mergedArray中
print(mergedArray) # 输出 [1, 2, 3, 4, 5, 6]
