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() methodmdn object assign
The Object.assign() method copies all enumerable own properties from one or more source objects to a target object. It returns the target object.
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 }
console.log(returnedTarget);
// expected output: Object { a: 1, b: 4, c: 5 }Copyright © 2021 Codeinu
