It basically is a way to use variables as the key selector.

In the example we might get getProperty from a function (like a select list)

So we can't do { name } as we don't know if it's name or age for instance. This way you can use a dynamic name (variable) to be the destructure selector.

Hope that makes a some sense?

Okay Chris Bongers. It's similar to Destructuring with a different name. We are storing the name with a different variable and using that variable to get another variable which will be used to get the value "Chris".

It took longer to understand. But, I hope my explanation makes sense :)
