  6. Now, here inside script tag we write JavaScript code. As you see there we create an array named array using var. After that we store value inside this under id and name. We store three arrays there.
  7. After that we to remove array we use splice on array and use (0,1) inside splice. It means that index is 0 there are count is 1.
  8. So, we conclude that the remove or say deletion start from first index and number of elements which we want to remove are 1. Hence, in output id 1 having name Robert must be removed from there.
  9. After that we use console to print or display output. You can see output by inspecting them and by opening console tab.
  10. At last, the <body> and <html> tags are closed with </body> and </html> respectively.
