SonarCloud Analysis and Report Review

Detected Problems and the Explanation:

1. EmployerTable.js - Unused Import 'FormControlLabel' and 'Switch'

These imports are not used in the code, indicating potential dead code. Removing them will lead to a cleaner codebase and reduce unnecessary dependencies.

2. backend/db/User.js - Expected Promise Rejection to be an Error

This issue suggests that a rejected Promise should ideally be an instance of the Error class. Make sure that Promise rejections are properly handled and communicated as Error instances.

3. backend/db/connect.js - Use 'let' or 'const' for 'dbPassword' Declaration

This recommendation encourages using 'let' or 'const' instead of 'var' when declaring variables. This enhances code readability and adheres to modern JavaScript standards.

4. backend/routes/apiRoutes.js - Remove Useless Assignment to 'candidateList' Variable

Removing the assignment to the 'candidateList' variable can improve code clarity and maintainability. Unused assignments can clutter the codebase.

5. backend/routes/apiRoutes.js - Remove Commented-Out Code

Removing commented-out code helps maintain a clean and readable codebase. Such code serves no purpose and can lead to confusion.

6. backend/routes/apiRoutes.js - Refactor Function to Reduce Cognitive Complexity

This message suggests refactoring a function to reduce its cognitive complexity. Complex functions can be harder to understand and maintain.

7. backend/routes/apiRoutes.js - Remove Redundant Jump

Removing a redundant jump in the code can improve its clarity and efficiency. Redundant code blocks can confuse developers and make the code less efficient.

8. frontend/src/App.js - Remove Useless Assignment to 'styles' Variable

Removing assignments to unused variables, such as 'styles', improves code clarity and helps identify variables that are actually in use.

9. frontend/src/views/Employer/AddJob.js - Remove Unused Import of 'useEffect'

Importing unused modules can add unnecessary dependencies and bloat to your code. Removing such imports improves the codebase's efficiency.

10. frontend/src/views/Home.js - Missing "key" Prop for Element in Iterator

When rendering elements in a loop (such as a map function), each rendered element should have a unique "key" prop. This aids in React's rendering performance and helps maintain component state.
