In this lab, you'll practice writing functions that have a callback as one of their parameters. While there's not much code to write, this lab will likely be conceptually quite tricky.
-
Fork and clone this repository.
-
Navigate to the cloned repository's directory on your command line. Then, run the following command:
npm install
This will install the libraries needed to run the tests.
-
Open up the repository in VSCode. Follow the instructions below to complete the Lab.
You'll complete the functions inside of the index.js
file. For each function, you will have the majority of the code already there. You should not change any of the existing code and instead just add the one to three lines, where specified, that will use the callback.
Instructions and examples can be found in both the index.js
file and the test files.
To run the tests, you can run the following command from the command line. You will need to be in the root directory of your repository.
npm test
This will run the test output once.
If you'd like, you can have the tests run constantly. This means that each time you save your file, your tests will re-run. To do so, you can run the following:
npm run watch
Follow the on-screen prompts to exit out of the constant runner.
