You can try the following code, it should work.

 let i = new I();
 //const clone = Object.assign({}, i);
 //arr.push(clone);
 //const clone = JSON.parse(JSON.stringify(i));
 //arr.push(clone);
 const clone = Object.create(
      Object.getPrototypeOf(i), 
      Object.getOwnPropertyDescriptors(i) 
  );
 arr.push(clone);
