  bar: {
    baz: {
      beep: 'boop'
    }
  }
};
 
console.log(deep(obj, 'foo'));
// => "bar"
 
console.log(deep(obj, 'bar.baz.beep'));
// => "boop"
 
console.log(deep(obj, 'foo.beep.boop'));
// throws
 
console.log(deep(obj, 'foo.beep?.boop'));

API

deep(obj, prop)

Access obj's property prop. The property string may contain key names, dots and question marks. If a key ends with an question mark but doesn't exist, the algorithm aborts and returns what it last got.
