Within my code, I am utilizing both a function and a loop:
var songs = Musics.searchSongs(query).then(function(rs) {
return rs;
});
for (var i = 0; i < songs.length; i++) {
console.log(songs[i]);
}
I am now looking for a way to execute the loop with the data returned from running the function. How can this be accomplished?
When dealing with asynchronous calls, it's important to remember that you cannot simply return from them. One approach is to utilize a callback function to handle the results of an asynchronous call.
For example, in this scenario, you could define a function that takes an array of songs as input and outputs each song to the console. Then, you would pass this function as an argument to your asynchronous call.
function displaySongs(songs) {
for (var i = 0; i < songs.length; i++) {
console.log(songs[i]);
}
};
Music.retrieveTracks(query, displaySongs).then(function(results) {
displaySongs(results);
};
