Frequently Asked Questions

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every word, commonly used in headings. Sentence case capitalizes only the first letter of each sentence, as in normal prose.

Can I use this to format variable names for code?

Yes — camelCase and snake_case are common naming conventions in programming languages like JavaScript and Python respectively.
