Tell us what’s happening:

Your code so far

var myMusic = [
  {
    "artist": "Billy Joel",
    "title": "Piano Man",
    "release_year": 1973,
    "formats": [ 
      "CS", 
      "8T", 
      "LP" ],
    "gold": true
  }
  // Add record here
];

var myMusic = [
{
“artist”: “Billy Joel”,
“title”: “Piano Man”,
“release_year”: 1973,
“formats”: [
“CS”,
“8T”,
“LP” ],
“gold”: true
}

[“artist”:“Popo”,
“title”: “HOMEWORK”,
“release_year”:1679,
“formats” : [“OP”,“1T”,“IOP”],
“gold”:true// Add record here
];

This is what I have done so far but it seem not right , I got stuck here.
part that i don’t understand is that what do they mean by adding strings to it?
