Frequently Asked Questions

What is camelCase?

camelCase joins words together with no spaces, capitalising every word except the first (e.g. "helloWorld"). It is widely used for variable and function names in JavaScript, Java, and other languages.

What is the difference between PascalCase and camelCase?

PascalCase (also called UpperCamelCase) capitalises the first letter of every word, including the first (e.g. "HelloWorld"). It is commonly used for class and component names.

When should I use snake_case vs kebab-case?

snake_case uses underscores as separators and is common in Python, Ruby, and database column names. kebab-case uses hyphens and is standard for URLs, CSS class names, and HTML attributes.
