object clone javascript

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));let clone = Object.assign({}, objToClone);var x = {myProp: "value"};
var xClone = Object.assign({}, x);

//Obs: nested objects are still copied as reference.var x = {key: 'value'}
var y = JSON.parse(JSON.stringify(x))

//If you do not use Dates, functions, undefined, regExp or Infinity within your objectlet clone = Object.create(Object.getPrototypeOf(obj), Object.getOwnPropertyDescriptors(obj));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 }
