I've tried many ways. Was googled many blog posts, but found no way to get the target :(

推荐答案

您可以使用

You can make a copy of the data returned by the proxy using Object.assign():

const target_copy = Object.assign({}, my_proxy);

这将适用于现有的所有可枚举的自有财产代理/目标.

This will work for all enumerable own properties existing on the proxy/target.
