Deep copy in ES6 using the spread syntax

by

Use JSON for deep copy

var newObject = JSON.parse(JSON.stringify(oldObject))


var oldObject = {
  name: 'A',
  address: {
    street: 'Station Road',
    city: 'Pune'
  }
}
var newObject = JSON.parse(JSON.stringify(oldObject));

newObject.address.city = 'Delhi';
console.log('newObject');
console.log(newObject);
console.log('oldObject');
console.log(oldObject);
