Experiencing peculiar behavior with the delete keyword in JavaScript

Okay, so here's the deal...

var obj = people[0];
obj.oAuthID = null;
delete obj.oAuthID;

This code snippet returns...

{
  "uuid": "39b2b45f-1dde-4c9a-8765-1bc76f55848f",
  "oAuthID": null,
  "date": "2013-10-21T16:48:47.079Z",
  "updated": "2013-10-21T16:48:47.079Z",
  "id": "52655aefcc81bb9adc000001"
}

However, if I use this function to clone the object...

function duplicate(obj) {
    // Handling different types including arrays and objects
   // Cloning properties to a new object while ignoring certain ones
}

var newObj = duplicate(people[0]);
newObj.oAuthID = null;
delete newObj.oAuthID;

The result now is...

{
  "uuid": "39b2b45f-1dde-4c9a-8765-1bc76f55848f",
  "date": "2013-10-21T16:48:47.079Z",
  "updated": "2013-10-21T16:48:47.079Z",
  "id": "52655aefcc81bb9adc000001"
}

I'm tired of having to clone the object just to hide a property. Why do I have to go through all this? How can I make it simpler and more conventional?

Answer №1

Have you tested this code in various browsers to see if it behaves consistently with the delete operator? There can be inconsistencies across different browsers. Check here for more information.

You could try deleting the property as if the object were an array.

delete outObj['oAuthID'];

This approach might provide a more reliable outcome.
