Your code so far

var myMusic = [
  "artist": "Billy Joel",
  "title": "Piano Man",
  "release_year": 1973,
  "formats": [
  "gold": true
{"artist": "Deep Purple",
  title: "Smoke on the water",
  release_year: 1976,
  formats: ["CD", "8T", "LP"]

Hey @anusai29102000,

Remember that JavaScript Arrays are 0-index (zero-indexed), that means, when you are trying to access the first item inside an array or objects, it’s going to be 0, then the second object will be 1 and so on. So myMusic[1] will access the second one. Try myMusic[0]. Learn more about zero-indexed javascript here:

Array has a 0 index predictable order if used with numeric default keys.
Object keys order on the other hand is unpredictable.
The informations I have added are a little bit off topic but good to know.
