You can verify that code referencing is working by prompting {% data variables.product.prodname_copilot_short %} to add some commonly used code and checking the output in the log. 1. Create a file called `fizz-buzz.js` and open it in the editor. 1. Display the log as described in the previous section. 1. In the editor, type: ```javascript function fizzBuzz() ``` With a space after the closing parenthesis. {% data variables.product.prodname_copilot %} should suggest code to complete the function. Typically the suggestion will be a common implementation of the fizz buzz algorithm that will match publicly available code on the {% data variables.product.github %} website. 1. To accept the suggestion, press Tab. 1. Check whether any entries for similar code have been added to the log.
