7,124 PointsLooping through a jQuery collection: the code from the video works okay in the devTools but not in the Worskapces. Why?
I launched the Worskspace for this video and copied Treasure´s code correctly (even with the backticks):
$('a').each(function(index, link){
const url = $(link).attr('href');
$(link).parent().append((${url}));
});
When I refresh the preview it doesn´t work though. So I tried to copy the code correctly in the Console of devTools and refreshed the preview and all works well!
I was wondering: Why? It happened to me in several previous videos. That the exactly copied code would only work from the devTools console, but not from the Workspaces.
It usually gives me this error in the devTools console:
Uncaught SyntaxError: missing ) after argument list app.js.4
So I diligently check the line 4 in app.js every time, but there is nothing missing nor nothing wrong. It is a brain teaser indeed:)
Thank you for your explanation:) I love the courses!

7,124 PointsIt is working:) Hurray!
There was an error on line 4 in app.js. Originally it was this:
const $pdfCheckbox = $('<label><input type='checkbox'> Allow PDF downloads</label>');
This is the new corrected version:
const $pdfCheckbox = $('<label><input type="checkbox"/> Allow PDF downloads</label>');
I changed the single quotes into double quotes and added a closing slash and it started to work! I just copied this line from the index.html before and didn't think more about it until today.
Happy coding and bug finding:)!
