连接两个具有相同值的数组，并使用Javascript/Node.js将其添加到一个JSON中

const array1 = [1, 2, 3];
const array2 = [1, 2, 3];

const json = {};

const combinedArray = array1.concat(array2);

json.array = combinedArray;

const array1 = [1, 2, 3];
const array2 = [1, 2, 3];
const json = {};

const combinedArray = array1.concat(array2);
json.array = combinedArray;

console.log(json);

{
  "array": [1, 2, 3, 1, 2, 3]
}
