| Delete Properties from a JavaScript Object |
We can also delete properties from objects like this:
delete ourDog.bark;
The delete operator removes a property from an object.
Syntax
delete expression where expression should evaluate to a property reference, e.g.:
delete object.property
delete object['property']
Parameters
object
The name of an object, or an expression evaluating to an object.
property
The property to delete.
Example
var person = {name:'Jay', age:'52'};
delete person['age'];
console.log(person); //{name:'Jay'}
