Example 3: javascript object.assign

const target = { a: 1, b: 2 };
const source = { b: 4, c: 5 };

const returnedTarget = Object.assign(target, source);

console.log(target);
// expected output: Object { a: 1, b: 4, c: 5 }

var sheep={"height":20,"name":"Melvin"};
var clonedSheep=JSON.parse(JSON.stringify(sheep));

//note: cloning like this will not work with some complex objects such as:  Date(), undefined, Infinity
// For complex objects try: lodash's cloneDeep() method or angularJS angular.copy() method

Example 6: object.assign react js

'use strict';

let last = {lastName: 'Stark'};
let person = Object.assign(first, last);
ChromeSamples.log(person);
// {name: 'Tony', lastName: 'Stark'}
ChromeSamples.log(first);
// first = {name: 'Tony', lastName: 'Stark'} as the target also changed

// Merge multiple sources
let a = Object.assign({foo: 0}, {bar: 1}, {baz: 2});
ChromeSamples.log(a);
// {foo: 0, bar: 1, baz: 2}

// Merge and overwrite equal keys
let b = Object.assign({foo: 0}, {foo: 1}, {foo: 2});
ChromeSamples.log(b);
// {foo: 2}
