What is camelCase?

camelCase is a naming convention where the first word is lowercase and subsequent words start with uppercase letters, with no spaces or separators. Example: 'myVariableName'. It's commonly used in JavaScript and Java.

What is snake_case?

snake_case uses lowercase letters with words separated by underscores. Example: 'my_variable_name'. It's popular in Python and database column names.

What is kebab-case?

kebab-case uses lowercase letters with words separated by hyphens. Example: 'my-variable-name'. It's commonly used in URLs and CSS class names.

What is Title Case?

Title Case capitalizes the first letter of each word. Example: 'This Is Title Case'. It's used for headings, titles, and proper nouns.
