Where each case format is used
camelCase is the standard for variable and function names in JavaScript, Java, and many other languages. PascalCase (also called UpperCamelCase) is typically used for class and component names. snake_case is common in Python variable names and database column names. kebab-case is standard for URL slugs and CSS class names. Title Case is used for headings, and Sentence case for regular prose.
Why casing conventions matter
Consistent casing improves readability and follows the conventions expected by a given language, framework, or style guide. Mixing conventions within one codebase or document makes it noticeably harder to scan, and some languages/frameworks use case as a meaningful signal — for example, PascalCase for a React component versus camelCase for a regular JavaScript function.
Example
hello world example
camelCase: helloWorldExample snake_case: hello_world_example kebab-case: hello-world-example
Tips
- PascalCase and camelCase differ only in whether the first letter is capitalized.
- kebab-case is the safest choice for URL slugs since hyphens are URL-friendly and readable.
Frequently Asked Questions
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (helloWorld), while PascalCase starts with an uppercase letter (HelloWorld). Both capitalize subsequent words.
Does this handle punctuation and numbers?
Yes, punctuation is treated as a word boundary and numbers are preserved as part of the surrounding word.
