The right case for every text.
Headings, body text, labels and code all follow different conventions. Here is when to use each one.

They are naming styles used in code. camelCase joins words and capitalizes each one after the first. PascalCase capitalizes every word. snake_case joins lowercase words with underscores, and kebab-case joins them with hyphens.
No. The conversion happens in your browser and the text is never sent to a server.
