Frequently Asked Questions
What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word (like "This Is Title Case"). Sentence case only capitalizes the first letter of the sentence (like "This is sentence case").
Can I convert text in Microsoft Word?
Yes! In Word, select text and press Shift + F3 to cycle through cases. However, Word only supports UPPERCASE, lowercase, and Capitalize Each Word—not developer cases like camelCase.
Is camelCase the same as PascalCase?
No. camelCase starts with a lowercase letter (myVariable), while PascalCase starts with uppercase (MyComponent). Both are common in programming but have different conventions.
