Writing Cases
UPPERCASE for short labels and acronyms. lowercase for tags and emails. Title Case capitalizes the main words, as in headlines and book titles. Sentence case capitalizes only the first word and proper nouns, and is the most readable style for buttons and UI text.
Programming Cases
camelCase for JavaScript and Java variables, PascalCase for C# classes and methods, snake_case for Python variables and many database columns, SCREAMING_SNAKE_CASE for constants, and kebab-case for URLs, CSS classes and file names. Following your language's convention makes code easier for others to read.
