Node.js lodash clone() create a deep copy of an object

var _ = require('lodash');

// _.clone() will create a deep copy of an object allowing us to break the reference 
// to the original and then manipulate it without touching the source.
// use judiciously

var complexObject = {
  firstName: 'Bob',
  lastName: 'Smith',
  addresses: [/*from   w  w  w.j a  v a 2s. c  om*/
    { address1: '123 Main St',
      city: 'Chicago',
      state: 'IL',
      zip: '60614'
    },
    { address1: '123 Elm St',
      city: 'Chicago',
      state: 'IL',
      zip: '60614'
    }
      
  ],
  greet: function() { return 'Hello ' + this.firstName; }
};


var objectCopy = _.clone(complexObject);

console.log(objectCopy);
