Standard Capitalization Styles Explained

Title Case (AP / Chicago style): Capitalizes major words while keeping short prepositions and conjunctions (a, an, the, and, but, or, for, nor, on, at, to, from, by, in, of) lowercase unless they are the first word. Ideal for blog headlines, email subjects, and book titles.
Sentence case: Capitalizes the first letter of each sentence, keeping proper nouns intact. Used in standard English paragraphs and product descriptions.
camelCase & PascalCase: Removes spaces and capitalizes words. Common in JavaScript, TypeScript, and Java programming variables and class names.
snake_case & kebab-case: Uses underscores or hyphens to join words. Standard for Python variables, database columns, and SEO URL slugs.
