Ultimately, yes. You can use something like $.each() on an object, but it
just runs that same for loop internally - see the source code for $.each().

delete obj.x2;
or
delete obj['x2'];
Note that it is not an error if the property doesn't exist, so you don't
have to "protect" the delete with code like this:
if( 'x2' in obj ) delete obj.x2; // unnecessary precaution
