JavaScript Adding Items Dynamically
0
$begingroup$
For a homework assignment, I have to create a "TO-DO" list, which will add a list item to the unordered list dynamically using JavaScript. I'm looking for answers that will improve the efficiency of the code. Any and all suggestions are welcome and considered. Thank you!
