Frequently Asked Questions
What is camelCase?
camelCase starts with a lowercase letter and capitalizes the first letter of each subsequent word, with no spaces or separators. Example: myVariableName. It is the standard naming convention for variables and functions in JavaScript, Java, and TypeScript.
What is the difference between snake_case and kebab-case?
Both use lowercase words separated by a delimiter. snake_case uses underscores (my_variable_name) and is common in Python, Ruby, and database column names. kebab-case uses hyphens (my-variable-name) and is standard for CSS class names, HTML attributes, and URL slugs.
When should I use PascalCase?
PascalCase capitalizes the first letter of every word with no separators (MyClassName). Use it for class names, React component names, type definitions, and enum values in most programming languages.
What is title case vs sentence case?
Title case capitalizes the first letter of each major word (The Quick Brown Fox). Sentence case capitalizes only the first word and proper nouns (The quick brown fox). Title case is used for headings; sentence case is used for body text and UI labels.
Does this tool change the actual words?
No. Case conversion only changes letter casing and word separators. The words themselves stay the same. myVariable becomes my_variable in snake_case, not a different word.
