You can use either repl.it, Gitpod or Visual Studio Code for this execrise. Fork this Github repo. Once done, at the terminal, type in:

yarn install
yarn add jest

Each question is in a folder by itself. The question description and what's expected will be in the readme.md file. Each question will have an index.html file and script.js file. Follow the instructions carefully in the readme.md file. Do not change the script.js file unnecessarily (there are special code at the end of the script.js file, don't touch it!)

You can check if you done the question correctly by typing the following in the terminal:

npm test <folder name>

For example, if you wish to test if you get q1 correct, you will type in

npm test q1

If you just want to check all your answers, just type in the terminal:

npm test

To get new questions, open a NEW terminal and type in the terminal:

git fetch upstream
git merge upstream/main

If there are conflicts in script.js files, just use your original copies.
