If I declare the variable outside the click event handler then the append() method ignores the variable and only inserts the <li> tags.
Once the const variable declaration is cut and copied into the click event handler, then the code works as expected.
Shouldn't it work either way?
Thanks

If the assignment is done at the global level, it is performed as soon as the page loads. Since the user has not had time to input anything yet, the value will be empty.
But inside the event handler, the code only runs after the user puts something into the input and clicks on the button.
