snake_case to PascalCase

snake_case is common for Python variables, Ruby, database columns and many REST APIs; PascalCase is used for class, type and React component names. Moving data between languages, databases and APIs often means converting between the two.

Examples

snake_case PascalCase
user_profile UserProfile
order_item OrderItem
http_client HttpClient
api_response ApiResponse
blog_post BlogPost
