How to clone a javascript ES6 class instance

Question

How do I clone a Javascript class instance using ES6.

I\'m not interested in solutions based on jquery or $extend.

I\'ve seen quite old discussions of object

Answer 1

class A {
  constructor() {
    this.x = 1;
  }

  y() {
    return 1;
  }
}

const a = new A();

const output = Object.getOwnPropertyNames(Object.getPrototypeOf(a)).concat(Object.getOwnPropertyNames(a)).reduce((accumulator, currentValue, currentIndex, array) => {
  accumulator[currentValue] = a[currentValue];
  return accumulator;
}, {});
