copy of object code example

Example 1: copy object javascript

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

Example 2: copy object javascript

var x = {key: 'value'}
var y = JSON.parse(JSON.stringify(x))

//this method actually creates a reference-free version of the object, unlike the other methods
//If you do not use Dates, functions, undefined, regExp or Infinity within your object

Example 3: javascript clone object

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

//Obs: nested objects are still copied as reference.
