Uses Arpad Élo algorithm for matchmaking and ranking. More importantly, answers the question - Cats or Dogs?
This website shows a very simplistic approach towards understanding how the Élo algorithm functions. Users would be asked to compare two images, and depending upon their selection, the elo would increase/decrease for the respective assets.

• Backend using Firebase🔥.
• Server side scripting using JS.
• And obviously, you've got the Bootstrap4 on the front end, along with JQuery!

This section describes my method of programming this project. I have added comment lines as much as possible to ease readability.

• Begin Button: Contains onClick() attribute which starts the project. This function will NOT be used again for the remainder of the project.

• Battles: Both images contain onClick() attributes that trigger 2 functions - one for changing elo of the current matchup, one for showing the next matchup.

• index.js(): This file contains code to initialize certain variables, display the matchup, and finally commit the data.

• elo.js(): This file contains the code to the algorithm. The probability formula, and how Elo points are changed after user input.

• matchmaking,js(): This file contains the algorithm(lol) to the battle matchups. Might be a bit confusing.

• commit_data.js(): This file finally commits all the data to the DB. All battle data is stored in JSON objects which are pushed ONLY when all 10 battles have been successfully(to avoid internet drops, refresh clicks,CMD+W misclicks etc etc) completed by the user.

• graphs.js(): This file contains information on displaying the info. Thanks to Chart.js!.
