Demonstrating Example of the removeChild() Method in JavaScript

The following code shows an unordered list with some list items. When the user double clicks on a list item, the function f1() is called. The function calls the removeChild() method. As a result, that particular list item gets removed.

<html>
<head>
  <title>removeChild Method Demo</title>
  <script>
     function f1(index)
     {
	var x1=document.getElementById("d1");
	var x2=document.getElementById("t2");
        let num=Number(index);
        x2.removeChild(x2.childNodes[num]);
        num="";
     }
  </script>
  <style>
    .c1{
       border: 4px solid #33ff99;
       border-radius: 10px;
       background-color: #5566aa;
       color: #aaffff;
       font-size: 20px;
       text-align: center;
       margin:5px;
       padding: 10px;
      }
    .a1{
