Welcome to the GitHub repository for "Calculator," a project designed to showcase foundational web development skills using HTML, CSS, and JavaScript. This calculator offers a minimalist yet robust interface that balances simplicity with functionality, making it a perfect tool for everyday arithmetic tasks.
- Interactive UI: Utilizes button elements for user input, ensuring an interactive and responsive experience.
- Support for Basic Operations: Perform basic mathematical operations like addition, subtraction, multiplication, division, and modulo directly through the UI.
- Immediate Feedback: Real-time display updates showing the current calculation to keep users informed of the operation in progress. Advanced Features:
- Negation: Users can negate a number by pressing the ± button, making it easy to switch between positive and negative values.
- Decimal Operations: The calculator handles decimal points, allowing for more precise calculations involving fractions.
- Keyboard Support: For power users, this calculator also supports keyboard inputs for numbers and operators, streamlining data entry and making it more accessible.
- Error Handling: It provides immediate feedback on illegal operations, preventing user confusion and ensuring a smoother user experience.
- Visual Feedback for Button Presses: Buttons visually respond to clicks, which helps users see which operation is being processed.
- Event Listeners: The calculator uses event listeners extensively to handle user interactions such as button clicks and keyboard events, updating the display and internal state accordingly.
- State Management: Maintains state through variables representing current values, selected operator, and whether a result has been displayed. This ensures accurate calculations and seamless continuation of operations.
- Responsive Design: Adapts gracefully to different screen sizes and device orientations, ensuring it is as functional on a mobile phone as it is on a desktop.
