How Can You Modify Existing Object Properties Using Destructuring in ES6?

Extended Object Destructuring

In ES6, destructuring is a syntax that allows you to unpack values from an array or object into individual variables. While destructuring is incredibly convenient, it can be limited if you want to assign values to an existing object.

Consider the following scenario:

var foo = {
  x: "bar",
  y: "baz"
}

var oof = {}

Suppose you want to transfer the x and y properties from foo to oof using destructuring. A straightforward attempt might look like this:

oof{x,y} = foo

However, this will not work. So, how can you modify existing object properties using destructuring?

A Possible Solution

While not the most elegant approach, you can use a combination of destructuring and assignment to achieve the desired result:

({x: oof.x, y: oof.y} = foo);

This will read the x and y properties from foo and assign them to the corresponding properties on oof.

Alternative Approaches

Alternative approaches to updating object properties include:

oof.x = foo.x;
oof.y = foo.y;

or

['x', 'y'].forEach(prop => oof[prop] = foo[prop]);

These approaches may be more explicit and readable, depending on your preferences.
