Open up the repository in VSCode. Follow the instructions below to complete the Lab.
Complete each function inside of the src/ folder. The comments and tests will help you determine what each function requires.
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.
There are a lot of tests that are contained in this lab. You can run a single test file individually by putting the name of the file after npm test. You can even only put part of the file name.
npm test 01
After choosing a specific file to run, you can also specific which test you want to run, specifically. Add .only after either test or describe for the specific test you'd like to run.
test.only("should return an array of everyone's name who is in the line, in order", () => {This will either run the specific test or, in the case of adding .only to a describe, all of the tests for a specific function.
NOTE: Don't forget to remove this after you get the test to pass!
If you want to manually test out your file, you can do so by running the following command.
node index.js
The output will be printed to your terminal.
