Challenges I Ran Into

One of the key challenges while building the calculator was handling division by zero gracefully. Initially, the program would crash or produce incorrect results when attempting to divide a number by zero.

To overcome this, I implemented a conditional check in the JavaScript logic to detect such cases. Instead of performing the division, the calculator now displays an error message like

"Cannot divide by zero"

Another hurdle was ensuring the design looked consistent and responsive across different devices. I tackled this by fine-tuning the CSS, using flexible layouts like CSS Grid and media queries to ensure the interface adapts to various screen sizes.

Debugging minor issues, like event listeners not triggering properly for the buttons, also taught me the importance of meticulously testing each feature during development.
