I’ve solved it but this challenge question isn’t clear at all .

For those who show up after me. The code is:

playlistSongs.innerHTML = songsHTML;

The whole add thing through me for such a loop. got this through trial and error.

We have blurred this solution (with [spoiler][/spoiler] tags) so that users who have not completed this challenge can read the discussion in this thread without giving away the solution.

Add songsHTML to playlistSongs , by using the innerHTML property.

I would probably prefer

Assign songsHTML to the innerHTML property of the playlistSongs element.

I have been wondering;
what is the difference between ;
songsHTML = playlistSongs.innerHTML;
AND
playlistSongs.innerHTML = songsHTML;

I have been trying to make sense out of this for a while with no luck

This question is tricky but, It’s good to warm up the brain a bit :smiley:

Pelo que entendi eles dão as instruções tudo errado e ao contrário. parece que fazem de propósito. é horrível tentar aprender a programar com a lógica

My question is COMPLETELY different than this for Step 19!!! It’s as follows:

Step 19

The map() method is used to iterate through an array and return a new array. It’s helpful when you want to create a new array based on the values of an existing array. For example:

const numbers = [1, 2, 3];
const doubledNumbers = numbers.map((number) => number * 2); // doubledNumbers will be [2, 4, 6]

Notice that the map() method takes a function as an argument. This is called a callback function, which is a function that is passed to another function as an argument. In the example above, the callback function is (number) => number * 2, and it’s run on each element in the numbers array. The map() method then returns a new array with the results.

Pass in a callback function to the map() method. The callback function should take song as a parameter, use the arrow function syntax, and have an empty body.
