The JavaScript delete Operator

The delete JavaScript operator is used to delete a property from an object.

Say you have this object:

const car = {
  model: 'Fiesta',
  color: 'green'
}

You can delete any property from it, or method, using the delete operator:

delete car.model

You can also reference the property/method using the brackets syntax:

delete car['color']
