I need help creating a JavaScript for the following:

Add another Unordered List (using) after the Unordered List already in this html file. The new Unordered List lists at least three electronic product names. Set the class of this list to hot. Add list element salt in between pine nuts and honey. After Header 2() insert Header 3 (using) with text Electronics. Your script need to calculate the total number of groceries listed in the first Unordered List and display it in Header2 as shown in the book example, your script also need to calculate the total electronics in the second Unordered List and display the number in Header 3

Here is my HTML code:
