Use Ember Get For Nested Objects

Sometimes you have to get a variable from a nested object like this

const toys = {
  muppets: {
    ernie: {
      head: 'wide'
    }
  }
}

If you are not sure if the complete object exist, you will have to do something like this:

const ernieHead = (toys && toys.muppets && toys.muppets.ernie && toys.muppets.ernie.head) ? toys.muppets.ernie.head : undefined;
// Do more with ernieHead...

With Ember you can use the get-function:

const ernieHead = get(toys, 'toys.muppets.ernie.head');

So in a controller it would be like this:

import Ember from 'ember';
const { Controller, get } = Ember;

export default Controller.extend({
  getToys() {
    const ernieHead = get(toys, 'toys.muppets.ernie.head');
    // Do more with ernieHead...
  }
});
