Why there isn't quotes surrounding li here? '''javascript ul.removeChild(li); ? '''
But for example here there are quotes. '''javascript let li = document.createElement('li'); '''

Courses Plus Student 129 PointsHello. The reason why it doesn't have quotes is because you are defining the li here:
let li = document.createElement('li');
and you are using the li variable here:
ul.removeChild(li);
First, you define the variable li to "li" and use li as "li" in the other code.
Hope you understand.
