You can if the target is an object.

You will have to create a function in target to retrieve it, that's all.

Example:

class AnyClass {
   constructor() {
      this.target = this;

      return new Proxy(this, this);
   }

   get(obj, prop) {
      if (prop in obj)
          return this[prop];

      // your stuff here
   }

   getTarget() {
      return this.target;
   }
}

And then when you call:

let sample = new AnyClass;
console.log(sample.getTarget());

Will return you the target as you expect :)
