Object Key Order and Reflect.ownKeys

  1. const obj = { 11: 'eleven', 23: 'twenty-three', 1: 'one', 2: 'two', '-1': 'negative 1' };
  2.  
  3. console.log(Reflect.ownKeys(obj))

I noticed that for in.. over an object was giving me weirdly consistent results across all browsers the other day and stumbled upon this.

Great news, but it’s Reflect.ownKeys for me… now that IE11 is dying/dead.
