Sometimes an object contains some set of properties, but you want to destructure it changing the names.

For example some function name does not suit your naming convention, or you already have a variable with that name.

You can rename one of the fields using this syntax:

const person = {
  firstName: 'Tom',
  lastName: 'Cruise'
}

const { firstName: name, lastName } = person

name //Tom
lastName //Cruise
