The sub-properties of objects can be accessed by chaining together the dot or bracket notation. Here is a nested object:

Slightly confused…am Iclose?

  **Your code so far**


var myStorage = {
"car": {
  "inside": {
    "glove box": "maps",
    "passenger seat": "crumbs"
   },
  "outside": {
    "trunk": "jack"
  }
}
};

var gloveBoxContents = myStorage.car["inside"].glove_box;

Close.

But you can access the first property in the chain using dot notation – car.inside.

The second one in the chain you can’t access using dot notation, because an identifier with spaces can’t work using dot notation. To explain:

car.inside.glove box can’t work: you are saying you want the key glove on the object with the key inside on the object with the key car. And then you want to access a variable called box. So that doesn’t make sense.

And you can’t get around this by changing the name “glove box” to something else, which is what you’ve done here, that can’t possibly work. There is no property called “glove_box”
