HarmonyOS 深拷贝关于list类型如何处理？

Question

目前ArkTS不支持any类型，没办法在ets中写深拷贝逻辑，但是在ts文件中写深拷贝时，list数据类型又不支持，如何处理

Answer 1

参考：

function deepCopy(obj: ESObject): ESObject {
  if (typeof obj !== "object" || obj === null) {
    return obj;
  }

  let copy: ESObject;
  if (Array.isArray(obj)) {
    copy = [];
    for (let i = 0; i < obj.length; i++) {
      copy[i] = deepCopy(obj[i]);
    }
  } else {
    copy = {};
    for (let i = 0; i < obj.length(); i++) {
      let key:ESObject=obj[i];
      if (obj.hasOwnProperty(key)) {
        copy[key] = deepCopy(obj[key]);
      }
    }
  }
  return copy;
}
let arr1:Array<number> = new Array<number>(1, 2, 3);
let arr2:Array<number> = deepCopy(arr1);
arr2[2] = 4;

console.log('arr1: '+String(arr1));
console.log('arr2: '+String(arr2));
