Welcome to Scientific Calculator 2.0! This project is a sophisticated tool designed to offer a modern, reliable, and versatile solution for scientific calculations. Developed as a personal project to sharpen my JavaScript skills, it was built entirely from scratch without relying on tutorials. Notably, the calculator avoids using the eval function, despite its convenience, to prioritize security and performance. Given the short development timeline, the calculator may not be complete or free from errors, but it provides a robust foundation for scientific computation.

Difficulty: 5/10

• Sleek Design: The calculator boasts a clean and modern interface with vibrant, saturated colors to enhance usability and aesthetics.

• Wide Range of Functions: Covers most scientific operations, including trigonometric, logarithmic, and exponential functions, among others.

• No eval Used: For better security, the calculator does not utilize the eval function. All operations are manually implemented from the ground up, ensuring a safer and more controlled environment.

• Advanced Calculation Method: Implements the PostFix notation (Reverse Polish Notation) as discussed in "Data Structures & Algorithm Analysis in C++" by Mark Weiss, ensuring accurate handling of operator precedence.

• Adaptability: The design is fully responsive, providing an optimal experience across various devices, including desktops, tablets, and smartphones.

• Mouse and Keyboard Support: Fully supports both mouse and keyboard inputs, making it easy to use in different scenarios.

• Enhanced User Experience: Includes interactive behaviors and sound effects to make the calculation process more engaging and intuitive.

• HTML: Forms the structure of the calculator's interface.
• CSS: Used to style the interface with modern and vibrant aesthetics.
• JavaScript: Powers the calculator's functionality, implementing custom algorithms and handling user interactions.

The project is organized to separate concerns clearly, with distinct directories for HTML, CSS, and JavaScript files. This structure facilitates easy maintenance and expansion.
