This small application demonstrates how to just vanilla JavaScript to get user input from a UI and use it to perform calculations. This project implements the Bootstrap 4 framework as well. This project was done as course work for Brad Traversy's Modern JS course on Udemy, viewable at: https://www.udemy.com/share/101WqkAEAbdlZRQ3kF/. I have modified the original project as it was presented in the course so that it included a 'clear' button that would reset the entire application. The original project did not include such a button and had to be cleared either manually or by refreshing the html page in the web browser.
