Rock, Paper, Scissors, Lizard, Spock game in vanilla JS

Project Description

This repository is a Rock, Paper, Scissors, Lizard, Spock game that I built to practice my Vanilla JavaScript skills.

Rock, Paper, Scissors, Lizard, Spock is a game invented by Sam Kass and Karen Bryla as an improvement on the classic Rock-Paper-Scissors game due to the fact that when you know someone well enough, 75-80% of any Rock-Paper-Scissors games you play with that person end up in a tie.

Rules:

You can play this game vs the computer here. You make a selection, the computer will make a random selection and then reveal the result of the choices: You win, Computer wins or It's a draw.

I have documented the code in the index.js with comment blocks.

In the future, I would like to update this project to use Socket.io to allow two human players to play against each other. Feel free to fork the repo and make any additions/improvements as desired.
