How to remove an object's property

Question

I need to remove a property in an object but I don't want null value. For example

var ob={'name':"CIAO",'animal':'DOG','house':'HOUSE'}

for example I want eliminate 'animal'

delete ob.animal;

the new Object is:

{'name':"CIAO",null,'house':'HOUSE'}

I don't want this result I want this:

{'name':"CIAO",'house':'HOUSE'}

Anyone can help me?

I don't see this occurring in node, nor in any browser ... what environment is this occurring in for you — Jaromanda X

o be honest {'name':"CIAO",null,'house':'HOUSE'} is not even a valid object — Jaromanda X

Edit (after clarification of the question):

For deleting animal, you need this. It deletes the property animal.

delete ob.animal;

There is no null value in the object.

var ob = { 'name': "CIAO", 'animal': 'DOG', 'house': 'HOUSE' };
delete ob.animal;
document.write('<pre>' + JSON.stringify(ob, 0, 4) + '</pre>');
document.write(ob.animal + '<br>');
document.write(typeof ob.animal);
