Someone help me with the following code:

Use your editor to open the bc_fed_txt.html and bc_keys_txt.js files from the html12 ? review folder. Enter your name and the date in the comment section of each file, and save them as bc_fed.html and bc_keys.js respectively.

2

Go to the bc_fed.html file in your editor. Directly above the closing tag, link the page to the bc_keys.js JavaScript file, loading the file asynchronously. Take some time to study the contents of the HTML file and then close it, saving your changes.

3

Go to the bc_keys.js file in your editor. Add event listeners to run the findKeyWords() and makeKeyStyles() functions when the page is loaded.

4

Create the findKeyWords() function to locate the keywords from the document and generate the keyword list. Within the findKeyWords() function, perform the tasks described in steps 5 through 10.

5

Create an aside element with the ID keywords and containing an h1 heading with the text Keyword List.

6

Create an ol element and append it to the keywords aside element.

my code won't work:

js:

"use strict";
