Choose meaningful identifier names

Names for variables, methods, and classes should be descriptive, semantically accurate, and consistent with established conventions. Follow these guidelines:

1. Use names that clearly describe the purpose or content:

   // Bad
   const val: any = getValue();
      
   // Good
   const fileOrFiles: File | File[] = getUploadedFiles();
   

2. Follow semantic naming conventions:
   • Boolean variables/methods should use “is”, “has”, or “should” prefixes
   • Error classes should be specific (e.g., RouterAliasError instead of Error)
   • Maintain consistent pluralization (e.g., PostsService for a service handling multiple posts)
3. Align with framework and library conventions:
   • Match external library naming patterns when extending their functionality
   • Follow project’s established naming patterns for consistency
   • Preserve meaningful naming from referenced libraries
4. Avoid generic or ambiguous names:
   • Replace generic names like ‘data’, ‘value’, ‘info’ with context-specific alternatives
   • Use type-specific prefixes/suffixes when appropriate
   • Consider the scope and usage when choosing names

Remember that good names serve as self-documentation and improve code maintainability.
