使用ts代码，将两个数组[1,2,3],['aaa','bbb','ccc']合并成[{aaa:1},{bbb:2},{ccc:3}]

可以使用map函数和Object构造函数实现：

const arr1 = [1,2,3];
const arr2 = ['aaa','bbb','ccc'];

const mergedArray = arr1.map((element, index) => {
  return {[arr2[index]]: element};
});

console.log(mergedArray);
// Output: [{aaa: 1}, {bbb: 2}, {ccc: 3}]
