Programming Fundamentals: Arrays

Setup

  • Fork this repository and clone your forked version to your machine
  • Install dependencies by running the command below while in the project's root directory:

npm ci

Instructions

  • Read through the numbered comments in src/core.js to understand the core requirements of this exercise.

  • Write your code directly below the numbered comment.

  • Add console.log's to get visibility on your solution and run the file with the command node src/core.js

Example

// 1. Create a variable named hello with the value 'Hello'
const hello = 'Hello'
console.log(hello)

Running tests

  • When ready to test your solution is correct, run the test suite with the command npm test
  • To begin with, all of the tests will fail. You'll see red F's in your console, like the image below:

  • Your solution is complete when the red F's have been replaced with green .'s in your console, like the image below:

Formatting Tests

When you try to git commit any work you've staged using git add, there is an additional test that runs that checks the formatting of your work against a set of rules we've defined. To run these tests locally use the following:

$ npx eslint src

You will then need to resolve the errors before successfully committing your work. You can also do this automatically with this command - but try to understand what well-formatted code looks like so you don't simply rely on this magic fix!

$ npx eslint src --fix

NB: If you fix these formatting errors, don't forget to git add and then git commit your changes before git push back to your remote repository

Extension

  • If you finish the core criteria, you can follow the same development process for the src/extension.js file
  • To run the extension tests, use the command npm run test-extensions
