Script Preparation code:

var obj = {
  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...'

}

Tests:

Lodash cloneDeep
const before = _.cloneDeep(obj) obj.description = 'this has changed' const after = _.cloneDeep(obj) const hasChanged = _.isEqual(before, after)
Json clone
const before = JSON.stringify(obj) obj.description = 'this has changed' const after = JSON.stringify(obj) const hasChanged = before === after
