Why Format Your Code?

  • Error reduction: Proper formatting can help reveal structural issues in your code
  • Professional appearance: Clean, well-formatted code demonstrates attention to detail and professionalism

Formatting Best Practices

Consistent Indentation: Choose either spaces or tabs and use them consistently throughout your codebase.

Line Length: Keep lines under 80-120 characters for better readability, especially when viewing code on smaller screens.

Grouping and Spacing: Use empty lines to separate logical sections and add spaces around operators for better readability.

Consider Linting: For professional projects, consider using dedicated linting tools that enforce coding standards automatically.

Language-Specific Practices

Different programming languages often have their own formatting conventions:

  • JavaScript/TypeScript: Popular style guides include Airbnb, Google, and StandardJS
  • HTML/CSS: Indenting nested elements and properties improves structural clarity
  • SQL: Capitalizing keywords and aligning clauses helps highlight query structure
  • JSON: Consistent indentation is crucial for navigating complex data structures
