JS 代理和解构赋值

Question

As what i know js Proxies make possible to overload classic object getter with a function call.

So that we can do things like that :

const value = myProxy.value;

All that calling in fact the value getter function inside Proxy.

My question is ... is there a way to use the JS destructuring syntax with JS Proxies ?

So that we could do things like that :

const { value } = myProxy;

Based on my tests, the second way is not working.

Answer 1

It is working with a necessary implemented getter.

 const myProxy = new Proxy({}, { get: function(obj, prop) { return 42; } }), { value } = myProxy; console.log(myProxy.value); console.log(value);
