The main difference between camelCase and PascalCase is the capitalization of the first word:
- camelCase: The first word starts with a lowercase letter, and all subsequent words start with an uppercase letter (e.g., "thisIsCamelCase").
- PascalCase: All words, including the first one, start with an uppercase letter (e.g., "ThisIsPascalCase").
camelCase is commonly used for variable and function names in JavaScript, Java, and many other programming languages, while PascalCase is often used for class names, types, and React components.
