class A {    construct(name) {        console.log('name: ', name);        console.log('this: ', this)        this.name = name;    }    testFunction() {        console.log('testFunction')    }}const singletonify = (OriginalClass) => {  let i  return new Proxy(OriginalClass, {    construct (target, args) {      console.log('test')      console.log(args)      if (!i) i = Reflect.construct(target, args);      return i    }  })}singleA = singletonify(A)a = new singleA()Reflect.construct(target, args)執(zhí)行的時候為何class A中的construct沒執(zhí)行
