02 · The honest pitch

Why Case Converter?

The code cases understand words that are already joined. getHTTPResponse becomes get_http_response, not gethttpresponse, because the converter splits at lowercase-to-uppercase changes and at the end of an acronym run. It also collapses repeated spaces and mixed separators, so " first name " gives first_name with no doubled underscores. Conversions run in your browser as you click.

Frequently asked questions

Both remove spaces and capitalize each word. camelCase keeps the first word lowercase (orderTotal), PascalCase capitalizes it too (OrderTotal). In JavaScript and Java, camelCase is the norm for variables and functions, and PascalCase for classes and React components. C# uses PascalCase for most public names.
