What is PascalCase?
PascalCase (also called Upper CamelCase or CapWords) is a naming convention where every word — including the first — starts with an uppercase letter, with no spaces or separators between words. It is the standard for class names, components, and type definitions across many programming languages.
Example:
Input:
user profile component
Output:
UserProfileComponent
When Do Developers Use PascalCase?
| Language / Context | Usage | Example |
|---|---|---|
| JavaScript / TypeScript | Class names | class UserProfile { } |
| React / Vue Components | Component names | <UserProfile />, <NavBar /> |
| C# / .NET | Classes, methods, properties | GetUserData(), UserProfile |
| Java | Class & interface names | class UserAuthentication |
| Python | Class names (PEP 8) | class UserProfile: |
| TypeScript | Type & interface names | interface UserProfile, type UserId |
| C++ | Class names | class DatabaseConnection |
PascalCase Examples — Right vs Wrong

Frequently Asked Questions
What is PascalCase?
PascalCase is a naming convention where every word starts with an uppercase letter and words are joined with no spaces. Example: UserProfile, GetData. It is also called Upper CamelCase.
What is the difference between PascalCase and camelCase?
In PascalCase, every word starts with a capital (UserProfile). In camelCase, the first word is lowercase (userProfile). PascalCase is for class names; camelCase is for variables and functions.
Why do React components use PascalCase?
React requires component names to start with a capital letter to distinguish them from regular HTML elements. <UserProfile /> is a React component; <userProfile /> would be treated as an unknown HTML element.
Is PascalCase the same as CapWords?
Yes — CapWords is the Python community's name for PascalCase. Python's PEP 8 style guide recommends CapWords (PascalCase) for class names.
When should I use PascalCase vs camelCase?
Use PascalCase for class names, interfaces, types, and React components. Use camelCase for variables, functions, and object properties. The rule of thumb: if it is a 'thing' (class/type), use PascalCase; if it is an 'action' or 'value', use camelCase.
