Rename & Destructure Javascript Variables ES6

0 865

On the last post we have looked at a dead simple introduction to what destructuring actually is and how to destructuring JavaScript Objects. This post will look another case scenario which would be Rename & Destructure Javascript Variables ES6 at the same time.

Sometimes data comes back in some odd names, and you might not necessarily want to use a property key as the end variable name. Maybe you don’t like that variable name or it’s already taken in your scope.

const facebook = 'facebook.com';
const profile = {
  first: 'Panayiotis',
  last: 'Georgiou',
  links: {
    social: {
      twitter: 'https://twitter.com/panay_georgiou',
      facebook: 'https://facebook.com/panayiotisgeorgiou.net',
    web: {
      cv: 'https://www.panayiotisgeorgiou.com'
      blog: 'http://www.panayiotisgeorgiou.net'

On the above example, I have already used facebook as a variable.

What happens next ?

For sure I can’t use it again, but I’m stuck, why?

Because this object gives me Facebook as a key and this object gives me Facebook as a key.

What you can do about this?

You can rename them as you destructure the objects

So – I want the facebook property, but I want to call it fb.

const { facebook: fb } = profile.links.social;

The above code will pull the profile.links.social.facebook into a variable called fb.

That’s it for now.
