JavaScript Episode 1

In this exercise your objective will be to write a pairs() function.

pairs() has the following features:

  • It accepts an array of names: pairs(['Asis', 'Hamsa', 'Fawas', 'Mishmish'])

  • It returns a randomized pairing of the people in the list: [['Mishmish', 'Asis'], ['Fawas', 'Hamsa']]

  • It can handle an odd number of names: pairs(['Asis', 'Hamsa', 'Fawas', 'Mishmish', 'Hussein]) returns [['Mishmish', 'Fawas'], ['Asis', 'Hussein'], ['Hamsa']]

  • It returns an empty array if it gets passed nothing: pairs() returns []

Instructions

Tools

  • Install node: 
    $ brew install node
  • Install yarn: 
    $ brew install yarn --without-node

The Files

Fork this repository and clone your fork (make sure you clone it into your development directory):

$ git clone https://github.com/<your_username>/JSEpisode1.git

Inside you'll find two .js files:

  • pairs.js - this is the file you'll be editing
  • pairs.spec.js - this is a testing file. It checks that your pairs() function has the features discussed above.
    DO NOT EDIT THIS FILE

Running The Tests

Install all the requirements:

  1. Navigate to the project root (you'll find a file called package.json there).
  2. Install the requirments using yarn install.

Run the tests:

$ yarn test

This command will run the testing file and test your pairs() function to make sure it has all the required features.

You'll know when you're done when your code passes all the tests.
