进一步/递归对象解构

Question

我有这个：

const {ops} = getOplogStreamInterpreter(strm);

ops.del.subscribe(v => {
  console.log('delete happened 1.');
});

ops.insert.subscribe(v => {
  console.log('insert happened 1.');
});

ops.update.subscribe(v => {
  console.log('update happened 1.');
});

只是想知道是否可以以某种方式做到这一点：

const {{insert,del,update}} = getOplogStreamInterpreter(strm);

基本上进一步解构返回的对象。

我认为你可以这样做：

const { ops: { del, insert, update } } = getOplogStreamInterpreter(strm);

del.subscribe(v => {
  console.log('delete happened 1.');
});

insert.subscribe(v => {
  console.log('insert happened 1.');
});

update.subscribe(v => {
  console.log('update happened 1.');
});
