Frequently asked questions
What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word, commonly used for headlines. Sentence case only capitalizes the first letter of each sentence, like normal prose.
How does camelCase handle multiple words?
Words are split on spaces, hyphens, and underscores. The first word is lowercased and every following word is capitalized and joined with no spaces, e.g. 'hello world' becomes 'helloWorld'.
How does snake_case handle punctuation?
Words are split the same way as camelCase, then lowercased and joined with underscores, e.g. 'Hello World' becomes 'hello_world'.
