obj-assign

Object.assign copies all own enumerable values but does not copies getters, setters and other value descriptors. This library allows you copy with all property descriptors of object.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign#Description The Object.assign() method only copies enumerable and own properties from a source object to a target object. It uses [[Get]] on the source and [[Set]] on the target, so it will invoke getters and setters. Therefore it assigns properties versus just copying or defining new properties. This may make it unsuitable for merging new properties into a prototype if the merge sources contain getters.

Installation

npm install obj-assign

or

yarn add obj-assign

Usage

const assign = require('obj-assign');

const obj = Object.create({}, {
  bar: {
    enumerable: true,
    value: 'bar',
  },
  foo: {
    enumerable: true,
    get: function() {
      return this.bar;
    }
  }
});

const clone = assign({}, obj);

clone.bar = 'Hello World';

clone.foo // 'Hello World'
