Frequently asked questions
What is Title Case?
Title Case capitalizes the first letter of each major word. Short words like "a", "the", "and", "or" remain lowercase (except at the start of the title). Used for book titles, article headlines.
What is camelCase vs PascalCase?
camelCase starts with a lowercase letter; words after the first are capitalized: "myVariableName". PascalCase capitalizes every word including the first: "MyClassName". Both remove spaces.
What is snake_case used for?
snake_case uses underscores between words, all lowercase. Standard in Python variable names, database column names, and URL slugs.

Writing and publishing
Title Case: article headlines, book titles (AP/Chicago styles differ on which small words to capitalize). Sentence case: most blog posts and web content. ALL CAPS: acronyms, warnings, emphasis — use sparingly as it reads as shouting.
