The eight case modes
- UPPERCASE — every letter is capitalised:
HELLO WORLD. - lowercase — every letter is lower-cased:
hello world. - Title Case — the first letter of each word is capitalised:
Hello World. - Sentence case — only the first letter of each sentence is capitalised.
- camelCase — words join with no spaces, each new word capitalised except the first:
helloWorld. - PascalCase — like camelCase but the first word is also capitalised:
HelloWorld. - snake_case — words are lower-cased and joined with underscores:
hello_world. - kebab-case — words are lower-cased and joined with hyphens:
hello-world.
When to use each
Title Case suits headings and titles; Sentence case suits normal prose. camelCase, PascalCase, snake_case and kebab-case are the standard identifier styles of programming — camelCase and PascalCase in JavaScript, Java and C#, snake_case in Python and databases, and kebab-case in CSS class names and URLs.
