Case Converter

Case conventions are the silent rules of text. Prose uses Sentence case (capitals at sentence starts) and Title Case (capitals on significant words in headlines). Code uses a wider range: camelCase (variables in JavaScript), PascalCase (classes in many languages), snake_case (variables in Python, Ruby, C), kebab-case (CSS classes, URLs, file names), CONSTANT_CASE (configuration values, enum values). Getting the case wrong is one of the most common cross-language bugs.

Title Case rules vary by style guide. The Chicago Manual of Style capitalizes all significant words (nouns, verbs, adjectives, adverbs, pronouns) but not articles, conjunctions, or short prepositions. The AP Stylebook is similar but treats some short words differently. We use a common-sense rule that capitalizes the first and last words and all words except articles, short prepositions and coordinating conjunctions — close to Chicago.

Code-case conversions are useful when refactoring between languages (Python snake_case to JavaScript camelCase) or normalizing user input (turning 'My Awesome Project' into 'my-awesome-project' for a URL slug). The tricky part is detecting word boundaries — 'camelCase' splits at the uppercase letter, 'PascalCase' splits the same way, 'snake_case' splits at the underscore, 'kebab-case' at the hyphen. We handle all of these.
