What is camelCase?
camelCase is a naming convention where multi-word identifiers are written without spaces or punctuation, with each word after the first capitalized. For example, "user first name" becomes "userFirstName". It is called camelCase because the capital letters in the middle of the compound word resemble the humps of a camel.
Where is camelCase used?
camelCase is the standard naming convention for variables and functions in JavaScript, TypeScript, Java, and Swift. It is also used for JSON property names, CSS-in-JS properties, and React component props. Most JavaScript style guides (including Airbnb and Google) mandate camelCase for local variables and function names.
Frequently Asked Questions
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (userFirstName), while PascalCase starts with an uppercase letter (UserFirstName). PascalCase is typically used for class names and React component names, while camelCase is used for variables and functions.
Should I use camelCase for API field names?
It depends on your language ecosystem. JavaScript/TypeScript APIs typically use camelCase, while Python APIs use snake_case and C# APIs use PascalCase. Pick one convention and apply it consistently across your API.
