What is camelCase and when is it used?

camelCase joins words by capitalizing the first letter of each word except the first (e.g., "myVariableName"). It is widely used in JavaScript, Java, and Swift for variable and function names.

What is snake_case and when is it used?

snake_case separates words with underscores, all lowercase (e.g., "my_variable_name"). It is the standard naming convention in Python, Ruby, and database column names.

What is kebab-case used for?

kebab-case separates words with hyphens, all lowercase (e.g., "my-variable-name"). It is used in CSS class names, HTML attributes, URL slugs, and file names because it is URL-safe.

PascalCase (also called UpperCamelCase) capitalizes the first letter of every word (e.g., "MyClassName"). It is the standard for class names in most object-oriented languages including Java, C#, and Python.

What is sentence case vs title case?

Sentence case capitalizes only the first word and proper nouns (like a sentence). Title case capitalizes the first letter of every major word — used for book titles, headings, and article titles.
