// Keep a copy of the collection for tests
var collectionCopy = JSON.parse(JSON.stringify(collection));
// Only change code below this line
function updateRecords(id, prop, value) {
// First condition
if(collection[id][prop] !== "tracks" && value !== ""){
collection[id][prop] = value
// Second condition
}else if(collection[id][prop] === "tracks" ){
if(!(collection[id][prop].hasOwnProperty(prop))){
collection[id][prop] = value
}
//Third condition

collection[id][prop].push( value)
