Frequently Asked Questions

What is camelCase?

camelCase starts with a lowercase letter and capitalizes the first letter of each subsequent word, with no spaces. Example: myVariableName. It is the standard naming convention in JavaScript and Java.

What is the difference between PascalCase and camelCase?

PascalCase capitalizes every word including the first (MyVariableName), while camelCase keeps the first word lowercase (myVariableName). PascalCase is used for class names; camelCase for variables and functions.

What is snake_case used for?

snake_case uses underscores instead of spaces with all lowercase letters. Example: user_profile_url. It is the standard naming convention in Python and for database column names.

What is kebab-case?

kebab-case uses hyphens instead of spaces with all lowercase letters. Example: my-css-class. It is the standard for CSS class names, HTML attributes, and URL slugs.
