FAQ

Is PascalCase the same as Title Case?

No. Title Case keeps spaces between words (“My Variable Name”) while PascalCase removes them (MyVariableName). Title Case is for human-readable text; PascalCase is for code identifiers.

When should I use PascalCase vs snake_case?

Follow your language's convention. C#, Java, and TypeScript types use PascalCase. Python and Ruby use snake_case for most identifiers. Mixing conventions in the same codebase is considered bad practice.
