What each case is for

Title Case — headlines and article titles; short joining words such as “of” and “the” stay lowercase unless they open the title.
Sentence case — body copy, UI labels and email subject lines.
camelCase / PascalCase — JavaScript variables and component or class names.
snake_case / kebab-case — database columns, file names and URL slugs.
CONSTANT_CASE — environment variables and configuration constants.
