"Refactor JavaScript: Reduce Redundancy and Implement Modern Practices"

[Aayush2308]

Improve Code Efficiency and Maintainability

Our current JavaScript codebase has several areas that can be optimized for better efficiency and maintainability. The main issues include code duplication, redundant checks, and suboptimal use of modern JavaScript features. Specifically, we need to consolidate similar functions (like form validation), streamline event listeners, and utilize features such as optional chaining and arrow functions. There's also room for improvement in our DOM manipulation methods, particularly in the FAQ toggle and eco-tips slider functionalities. Additionally, we should enhance error handling in form validations and simplify calculations where possible (e.g., progress bar). By addressing these issues, we can significantly reduce the code's complexity, improve its performance, and make it more resistant to potential errors. These changes will not alter the existing functionality but will make the codebase more robust and easier to maintain in the long run.

Proposed Changes:

• Combine similar functions to reduce redundancy
• Consolidate event listeners under a single DOMContentLoaded event
• Implement optional chaining for safer property access
• Optimize loops and calculations
• Enhance form validation logic
• Improve error handling and user feedback
• Utilize modern JavaScript features for conciseness and clarity

Implementing these changes will result in a more efficient, maintainable, and error-resistant codebase without altering the current functionality of our website.
