Why Naming Conventions Matter

Consistent naming conventions improve code readability and team collaboration. Python and databases favour snake_case; JavaScript uses camelCase for variables and PascalCase for classes; CSS and HTML use kebab-case; constants are SCREAMING_SNAKE_CASE. Converting between them is a frequent task when integrating APIs, refactoring code, or writing config files.

Frequently Asked Questions

Both join words without spaces, but camelCase starts with lowercase (myVariable) while PascalCase starts with uppercase (MyVariable). JavaScript uses camelCase for variables and functions, PascalCase for classes and React components.
Google recommends hyphens in URLs. Search engines treat hyphens as word separators so my-blog-post is indexed as three words. Underscores are treated as word joiners so my_blog_post may be indexed as one word.
SCREAMING_SNAKE_CASE (uppercase with underscores) is the universal convention for constants and environment variables across most languages — Python (MAX_RETRIES), JavaScript (const API_URL), .env files. The uppercase signals the value should not change at runtime.
