Last post we took a look at an intro to destructuring. Let's take a look at another use case which would be renaming your variables. 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 twitter = 'twitter.com';
const wes = {
first: 'Wes',
last: 'Bos',
links: {
social: {
twitter: 'https://twitter.com/wesbos',
facebook: 'https://facebook.com/wesbos.developer',
},
web: {
blog: 'https://wesbos.com'
}
}
};
For example here, I already used twitter as a variable. I can't use it again, but I'm stuck, because this object gives me twitter as a key. What you can do is you can rename them as you destructure them.
So - I want the twitter property, but I want to call it tweet. I want the facebook property, but I want to call it fb
.
const { twitter: tweet, facebook: fb } = wes.links.social;
The above code will pull the wes.links.social.twitter into a variable called tweet and similarly fb for facebook
.
