I'm getting the following ESLint errors for unused variables in my project:

  3:10  error  'Tab' is defined but never used                           no-unused-vars
  3:15  error  'Tabs' is defined but never used                          no-unused-vars
  9:8   error  'AssessmentSelector' is defined but never used            no-unused-vars
  10:8  error  'AssessmentsTable' is defined but never used              no-unused-vars
  11:8  error  'ErrorBoundaryWrapper' is defined but never used          no-unused-vars
  12:8  error  'Loader' is defined but never used                        no-unused-vars
  13:8  error  'QuestionnaireDetailedResults' is defined but never used  no-unused-vars
  14:8  error  'QuestionnaireSummary' is defined but never used          no-unused-vars

I have checked my code, and these variables are imported or declared but not used anywhere. How can I fix these errors?

This issue arises because ESLint is enforcing the no-unused-vars rule, which flags any variables, imports, or components that are defined but not used in your code. This is often helpful to prevent unnecessary or redundant code, but it can be annoying when you are in the process of refactoring or temporarily not using a variable.

Here are several ways to resolve or suppress these errors:

Change ESLint Rule Configuration

If you prefer to keep the unused variables (perhaps for future use or refactoring purposes), you can modify the ESLint configuration to either:

• Warn instead of error:

  This will prevent the ESLint errors but still notify you about unused variables:

  In your .eslintrc.js or eslint.config.mjs, change the no-unused-vars rule to "warn":

  "no-unused-vars": "warn"
  

• Turn off the rule entirely:

  If you don't want ESLint to check for unused variables at all, you can disable the rule entirely:

  "no-unused-vars": "off"
  

Conclusion

• Best Practice: Remove unused variables or imports to keep your code clean and maintainable.
• Alternatives: If you prefer to keep the variables, you can adjust the ESLint rule settings to "warn" or "off" depending on your preference.
• Inline ESLint Disabling: For specific cases, you can disable the rule for a line or block of code using inline comments.
