Tell us what’s happening:

Your code so far

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

// Only change code below this line
myStorage.car.inside["glove box"] = "maps" ;

var gloveBoxContents = myStorage; // Change this line

Do you have a question or problem?

Basically, there are 2 ways of handling object properties:

  • using dot notation, eg.: myStorage.outside.trunk (returns “jack”)
  • using bracket notation, eg.: myStorage[“car”][“outside”] (returns “jack”)

The advantage of bracket notation is that you can feed it variables, e.g.:

var someVariable = "car"
myStorage[someVariable]
