One day I decided that I am subscribed to too many Youtube channels. When I started going through my subscription list I quickly noticed the process is very time consuming because a user has to click each individual unsubscribe button. That's when I decided to look for a solution which would allow me to unsubscribe from multiple Youtube channels at once. I found a forum post and some articles (here is one of them) where a solution is presented, but it involves copying code into the browser's console and I thougth about making it easier for the average user. I then decided to look into the Youtube Data API and quickly found out this wouldn't be that hard to do. So here's the finished product.
You will need to insert your own apiKey and clientId in the main.js file.
