[Feedback] Calculator Using Shunting Yard and Postfix Algorithms

Hey! As the title suggests, I’d like some feedback on my JavaScript calculator. I made it using the shunting yard and post-fix notation algorithms, which I believe is the best approach to actually calculating the totals.

If you check out the code, have a look at the src folder as I used Babel and Parcel, which minimizes the JavaScript for production.

The calculator is hard coded to support up to 3 decimal places.
