Frequently Asked Questions
Understanding text formatting casing rules.
What is the difference between camelCase, PascalCase, snake_case, and kebab-case?
These are standard variable naming conventions:
- camelCase: lowercase first word, capital first letters for subsequent words (e.g.
helloWorld). - PascalCase: capital first letters for all words (e.g.
HelloWorld). - snake_case: lowercase words separated by underscores (e.g.
hello_world). - kebab-case: lowercase words separated by hyphens (e.g.
hello-world).
How does Sentence Case work?
Sentence Case capitalizes the first letter of each sentence (after a period, question mark, or exclamation point) and converts the rest of the sentence to lowercase.
How does Title Case determine capitalization?
Title Case capitalizes the first letter of every word, except for short articles, conjunctions, or prepositions (like “a”, “an”, “the”, “and”, “but”, “for”, “at”, “by”, “to”) unless they start the sentence.
