What is the difference between camelCase and PascalCase?

In camelCase, the first word starts with a lowercase letter and each subsequent word is capitalized (e.g., myVariableName). In PascalCase, every word starts with a capital letter (e.g., MyVariableName). camelCase is common in JavaScript variables, while PascalCase is used for class names in C#, Java, and React components.
