Remove button just removing last button

I have tried the remove button, but it is removing only last item, not all. Here is my https://jsbin.com/binukaqivi/edit?html,js,output here is the code

var ul = document.getElementsByTagName("ul")[0]
var li = document.createElement("li");
var last = document.querySelector("li:last-child");

li.textContent = "I am new"
ul.appendChild(li);

var btn = document.getElementsByTagName("button")[0];


btn.addEventListener("click", function(){
  ul.removeChild(last);
})

The JSbin code and the code shown here are different, but neither one seems complete.

But perhaps most pertinent to your question is this line:

  ul.removeChild(last);

Clearly, this line is intended to remove only the last item. If you want to remove other items, you might use a loop to select them and remove each one.

Or you could get rid of them all at once by just giving the list empty contents:

  ul.innerHTML = "";
