Easiest way to achieve what you want is to use JSON.stringify with JSON.parse to create a unlinked copy of array of objects. const OBJ1 = (name, tags) => ({ myname: name, mytags: tags, myvalue: 0, }) function createarray1() { var myarray=[]; myarray.push(OBJ1("NAME", [...

对于引用(对象)类型来说,这种只是复制对象引用地址被称为浅拷贝(shallow copy),与之对应的,如果在堆中拷贝了一模一样的数据则被称为深拷贝(deep copy)。 将对象数据保存在堆中能大大节省内存空间,如果整个中国的名单保存在变量中,使用栈来保存则每次复制会拷贝整个数据(每次调用函数传参也属于执行了一次复制),内存...
