when sort button is clicked, word list sorted but with null words as well.

sort button listens 'click', and it sort out word list but it includes null from localStorage as well.

you can just clear your local storage or use a different browser to get us ready for the presentation
or
null is still an entry can you console.log the array and maybe you can add an if check in the render function that ignores empty strings as quick fix
