    'name': 'David',

    'age': 29,

    'education': {'degree': 'M.B.B.S', 'profession': 'Doctor'}

    'c': {

      'd': 'd',

      'e': 'Hello {c.d}',

      'f': 'Hi "{a}", am I deep enough, or need to show "{c.e}" with {b}'

    }

  };

  // traverse the object

  print(interpolation.traverse(obj, 'b'));

  // output: 10

  print(interpolation.traverse(obj, 'c.e'));

  // output: Hello {c.d}

  print(interpolation.traverse(obj, 'c.g')); // not present

  // output: (empty string)

  print(interpolation.traverse(obj, 'c.g', true)); // not present but keepAlive

  // output: {c.g}

  // resolve the object

  print(interpolation.resolve(obj));

  // output: {a: a, b: 10, c: {d: d, e: Hello d, f: Hi "a", am I deep enough, or need to show "Hello d" with 10}}

  print(obj);

  // original object is not changed

  // output: {a: a, b: 10, c: {d: d, e: Hello {c.d}, f: Hi "{a}", am I deep enough, or need to show "{c.e}" with {b}}}

}
