Issue #242  (ES6 Object Destruct, Uncats, CSS, React)

Continuing on the topic of ES6 destructuring, the power of destructuring is evident in the ability to navigate into nested object structures to get specific bits of information as needed.

For example, let's say you have the following object:

let myObj = {
  name: "Pat",
  location: "Earth",            

  status: {
    initial: {
      start: 1,
      end: 2
    },

    other: {
      start: 10,
      end: 20
    }
  }

};

Using destructuring, you can assign deeply nested values from this object to variables for use later in your code:
 
let { status: { initial }} = myObj,
    { status: { other }} = myObj;

console.log( initial.start ); // 1
console.log( other.end ); // 20

In previous destructuring examples, the element(s) inside the first curly brace represented the variable(s) that would be used to hold the destructured value(s). In this case, however, the variable is inside another nested set of curly braces. The first thing before the colon here indicates the object where you want to start searching.

Each nested set of curly braces allows you to go deeper into the object. You can then use dot notation to access the property you want, as I've done in the code above when logging the values.

If you want to use a different variable name for the object you're accessing,  you can do this:
 
let { status: { initial: initialValue }} = myObj;

console.log( initialValue.end ); // 2

In this case, I'm assigning the status.initial object to a variable called initialValue. This adds a little extra complexity to the process, and might make the code a little harder to maintain, but it's an option if that's something you need to do.
