Frequently asked questions
What text cases can I convert between?

What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word (e.g. "The Quick Brown Fox"). Sentence case only capitalizes the first word (e.g. "The quick brown fox"). Title case is used for headings and titles; sentence case is used for normal prose.
When would I use camelCase vs snake_case?
camelCase is common in JavaScript, Java, and Swift for variable names (myVariableName). snake_case is standard in Python, Ruby, and Rust (my_variable_name). kebab-case is used in URLs, CSS classes, and file names.
