Responsive calculator with a slider to switch between three themes

What are you most proud of, and what would you do differently next time?

I’m proud of how I applied various JavaScript features and CSS techniques to build a clean, functional UI. I handled theme switching using objects and ensured responsiveness through CSS which is something I’m particularly happy with.

Next time, I would explore creating this application using another library such as React for a more component-based architecture and easier state management.

What challenges did you encounter, and how did you overcome them?

One challenge I encountered was trying to understand how to manage and apply different themes. Initially, I found it tricky to structure my themes in a way that allowed for easy switching and dynamic updates. I overcame this by using JavaScript objects to store each theme as a collection of key-value pairs. Each key represented a CSS variable, and its value was the corresponding color or style for that variable.
