Use toolFrequently asked
What is the difference between Title Case and Sentence Case?
Title Case capitalises every word (Every Word Like This). Sentence Case capitalises only the first word of each sentence (Every word like this).
How does camelCase handle spaces?
All spaces and punctuation between words are removed, the first word is lowercased, and each subsequent word starts with an uppercase letter: 'hello world' → 'helloWorld'.
