常见问题

When should I use camelCase vs snake_case?

camelCase is common in JavaScript, Java, and TypeScript. snake_case is preferred in Python, Ruby, and database column names. Follow your language's conventions.

What is PascalCase used for?

PascalCase (also called UpperCamelCase) is typically used for class names, components (like React components), and type definitions in TypeScript.

Why use kebab-case for URLs?

Kebab-case is URL-friendly as hyphens are allowed in URLs without encoding, and search engines treat hyphens as word separators for better SEO.
