clone object in js
var student = {name: "Rahul", age: "16", hobby: "football"};
//using ES6
var studentCopy1 = Object.assign({}, student);
//using spread syntax
var studentCopy2 = {...student};
//Fast cloning with data loss
var studentCopy3 = JSON.parse(JSON.stringify(student));javascript clone object
var x = {myProp: "value"};
var xClone = Object.assign({}, x);
//Obs: nested objects are still copied as reference.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() methodjavascript clone object
let clone = Object.create(Object.getPrototypeOf(obj), Object.getOwnPropertyDescriptors(obj));javascript clone object
// syntax: let <newObjectName> = {...<initialObjectName>};
// example:
const me = {
name: 'Jakes',
age: 30,
};
const friend = {...me};
friend.age = 27;
console.log(friend.age); // 27
console.log(me.age); // 30
// -----------------------------
// BAD

const me = {
name: 'Jonas',
age: 30,
};
const friend = me;
friend.age = 27;
console.log(friend.age); // 27
console.log(me.age); // 30Copyright © 2021 Codeinu
