How to remove entry from an object

Question

How do I remove an entry, such as [2] from below?

var object = {};
object[0] = true;
object[1] = true;
object[2] = true;

Answer 1

This will work:

delete object["2"]

I would suggest you don't use "object" as your variable name. "object" is a reserved word.

Also, see this question: how-to-remove-a-property-from-a-javascript-object

EDIT:

Actually "object" is not on the list of reserved words. But "Object" (capital "O") does have a meaning in JavaScript. So I would discourage using that name anyway.

Answer 2

To remove object properties, use delete, like this:

delete object[2];
