Tell us what’s happening:
I understand I need to use if and else if statements but I don’t understand the logic of the conditions and the syntax.
So far I have done this code, I watched the video but I don’t want to copy code, I do really want to understand what is happening, please explain
function updateRecords(id, prop, value) {
if (prop != “tracks” && “tracks” != );
return collection;
}
else if (prop != “tracks” && value !== “”) {
}
else (value !="") {
delete prop[value];
}
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"
}
};
// Only change code below this line
function updateRecords(id, prop, value) {
if (prop != "tracks" && "tracks" != []);
return collection;
}
else if (prop != "tracks" && value !== "") {
}
else (value !="") {
delete prop[value];
}
updateRecords(5439, "artist", "ABBA");
