How to destructure object and make alias for keys name

#javascript

Let say you have object that look like this:

const userData={firstName:'John',lastName:'Doe',country:'Ireland'}
Enter fullscreen mode Exit fullscreen mode

Then you want to destructure this object and change country key name with nationality, here how to do that

let {firstName,lastName,country:nationality} = userData /* firstName 'John' lastName 'Doe' country Uncaught ReferenceError: country is not defined --> because we don't declare country variable nationality 'Ireland' */
Enter fullscreen mode Exit fullscreen mode
