Social Media Tracker Using Sass and Vanilla JS

Hey Shubham, nice to see you post a new solution. Where have you been learning JS? Your code looks fine, but I'd say you've over-engineered the solution in this instance. You don't need so much JS code to switch between a light and a dark theme. You can simply use it to toggle a class or HTML attribute and then use CSS custom properties to take care of the color changes.

Here's a great article that runs through this approach: https://hankchizljaw.com/wrote/create-a-user-controlled-dark-or-light-mode/

I hope this helps!
