Not working JS script printList

Hello everyone, I don't know why, but for me, JS Script printList from file helpers.js is not working. I did assign it in HTML file, but in a console, it shows. "printList is not defined at playlist.js:4" HTML file: <scrit src="js/helpers.js"></scrit> <script src="js/playlist.js"></script>

playlist.js : var playList = []; playList.push("I Did It My Way");

printList( playList);

I have checked, the file is assigned correctly, camelToe is used everywhere. I don't know, what causes that problem, any ideas? Or it is just a bug from Chrome?

Not sure. I'd have to see the complete code.

It looks like you have

<scrit src="js/helpers.js"></scrit>

instead of

<script src="js/helpers.js"></script>

Javascript is case sensitive. You declared playlist with a lowercase l. But then you use methods on playList with an uppercase L. This results in error: Uncaught ReferenceError: playList is not defined.

Change the l to uppercase in your first two lines of code so you have:

var playList = [];
playList.push('I did it my way');
playList.push('Respect','Imagine');
playList.push('Johana');
playList.unshift ('Born to run');

printList( playList );

You're absolutely right Kris, thanks a lot. Oh by the way, I have a " > " signal appearing at the end of the list, could you please check again and let me know why?

Thanks again

Omar

This is not an answer, is a question

var playlist = []; playlist.push ('I did it my way'); playList.push ('Respect','Imagine'); playList.push('Johana'); playList.unshift ('Born to run');

printList( playList );
