This is a vanilla JavaScript calculator app that allows users to switch between 3 nice-looking themes, provides basic arithmetic operations, and provides the ability to see a history of the last 5 calculations performed. The app is written in an MV* variation architecture, implements a PubSub class to manage communication of data from the Model to the listening views whenever the state changes. A HistoryManager class is also included to handle the history logic of the performed calculations and is separated from the Model class for better separation of concerns.

In future developments, I would like to add more complex operations and advanced functionalities to the calculator, such as the ability to calculate percentages, square roots, and exponents.
