If you have your file structure as shown below:

• Parent Folder
  • HTML File
  • JSON File

Then navigate to the Parent Folder in your File Explorer and within your terminal, run:

#Replace local_num with some number (I used 1337)
python -m http.server [local_num]

This is another test line to see how this would work with the updating of two repositories.
This is a test edit to see how this goes. This is another test line to make sure that this is adding properly.
Then, in your browser, go to http://localhost:1337/index.html, where you can replace the 1337 portion of the URL with your local_num that you selected earlier.

This is the only way for you to be able to see the JavaScript Code successfully load the JSON Data
