how to copy key of object to another object code example

Example 1: copy object javascript

// es6
const obj = {name: 'john', surname: 'smith'};
const objCopy = {...obj};

Example 2: javascript clone object

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
