Frequently Asked Questions
- What is camelCase?
- camelCase is a naming convention where the first word is lowercase and each subsequent word starts with a capital letter, with no spaces. Example: myVariableName. It is widely used in JavaScript, Java, and JSON.
- What is the difference between camelCase and PascalCase?
- Both remove spaces and capitalize each word. The difference is the first word: camelCase starts lowercase (myVariable), while PascalCase capitalizes the first word too (MyVariable). PascalCase is used for class names and React components.
- What is snake_case used for?
- snake_case uses underscores between words with all lowercase letters. It is the standard naming convention in Python, Ruby, and most database column names.
- What is kebab-case?
- kebab-case uses hyphens between lowercase words, resembling items on a kebab skewer. It is used for CSS class names, HTML attributes, and URL slugs.
- What is title case?
- Title case capitalizes the first letter of each significant word. Articles, prepositions, and conjunctions under 4 characters (a, an, the, and, but, or) are not capitalized unless they are the first word.
