Frequently asked questions
What is the difference between camelCase and PascalCase?
Both remove spaces and capitalize word boundaries. camelCase starts with a lowercase letter (myVariableName) and is common for variables in JavaScript and Java, while PascalCase starts with an uppercase letter (MyClassName) and is common for class names.
Does Title Case capitalize every word?
This tool capitalizes the first letter of every word, which is the simplest and most widely used convention. Editorial styles like AP or Chicago lowercase short words such as "a" and "of" — adjust those manually if your style guide requires it.
