I found a great way to get the original target by defining the getPrototypeOf handler:

function createProxy() {

  const myArray = [Math.random(), Math.random()];

  return new Proxy(myArray, {

    getPrototypeOf(target) {

      return target;

    }

  });

}



const myProxy = createProxy();

const target = Object.getPrototypeOf(myProxy); // will get the original array
