## Data hijacking

Vue internally uses `Obeject.defineProperty()` to implement two-way binding, which allows you to listen for events of `set` and `get`.

* It can only implement data hijacking on properties, so it needs deep traversal of the entire object
* it can't listen to changes in data for arrays

On the other hand, `Proxy` doesn't have the above problem. It natively supports listening to array changes and can intercept the entire object directly, so Vue will also replace `Obeject.defineProperty` with `Proxy` in the next big version.

反观 Proxy 就没以上的问题，原生支持监听数组变化，并且可以直接对整个对象进行拦截，所以 Vue 也将在下个大版本中使用 Proxy 替换 Obeject.defineProperty
