"Refactor JavaScript: Fix event handling, optimize DOM operations, and reduce code duplication"

[Aayush2308]

Is there an existing issue for this?

• [X] I have searched the existing issues

What happened?

1. Inconsistent event listener usage, with some listeners attached outside the DOMContentLoaded event.
2. Inefficient DOM manipulation methods (e.g., using innerHTML instead of textContent).
3. Redundant code in the "Learn More" and "Show Less" functionality.
4. Repetitive code in form reset and error handling.
5. Inconsistent naming conventions (mixing camelCase and lowercase).
6. Suboptimal scoping of functions and variables.
7. Use of older JavaScript syntax where more modern alternatives exist.

Addressing these issues will improve code efficiency, readability, and maintainability. Proposed changes include consolidating event listeners, optimizing DOM interactions, reducing code duplication through function refactoring, and adopting more consistent naming and modern JavaScript practices. These improvements will not alter the existing functionality but will make the codebase more robust and easier to work with in the future.
