Script Preparation code:
 
var MyObject = {
  description: 'Creates a deep copy of source, which should be an object or an array.',
  myNumber: 123456789,
  myBoolean: true,
  jayson: {
    stringify: 'JSON.stringify() method converts a JavaScript value to a JSON string....',
    parse: 'JSON.parse() method parses a JSON string...'
  }
};
var myCopy = null;
Tests:
  • Lodash cloneDeep

     
    _.isEqual(MyObject, MyObject);
  • Json clone

     
    JSON.stringify(MyObject) === JSON.stringify(MyObject);
