Tell us what’s happening:
Hello everyone,
I’ve tested the code below in the browser’s console and it passes all tests, however in the emulator here on freeCodeCamp it does not pass:
After updateRecords(2468, “tracks”, “Free”), tracks should have “1999” as the first element.
Any ideas why?
Your code so far
// Setup
var collection = {
"2548": {
"album": "Slippery When Wet",
"artist": "Bon Jovi",
"tracks": [
"Let It Rock",
"You Give Love a Bad Name"
]
},
"2468": {
"album": "1999",
"artist": "Prince",
"tracks": [
"1999",
"Little Red Corvette"
]
},
"1245": {
"artist": "Robert Palmer",
"tracks": [ ]
},
"5439": {
"album": "ABBA Gold"
}
};
// 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) {
if (value === "") { // if the value is "" delete the property
delete collection[id][prop]
console.log(collection)
return collection
}
if (!collection[id].hasOwnProperty(prop)) {
console.log('Property does not exist, adding it ..')
if (prop === 'tracks') { // if it's tracks that does not exist, create the array with the value..
collection[id][prop] = [value]
console.log(collection)
return collection
}
collection[id][prop] = value
console.log(collection)
return collection
} else {
if (prop === 'artist') {
collection[id][prop] = value
console.log(collection)
return collection
} else if (prop === 'tracks') { // if it's tracks and it exists, put the value first in the arr
collection[id][prop].unshift(value)
console.log(collection)
return collection
}
}
return collection;
}
// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");
