What is UPPERCASE?
UPPERCASE (also known as capital letters or all caps) is a text format where all letters are converted to their capital form. Each lowercase letter is replaced with its corresponding uppercase equivalent, while numbers, symbols, and spaces remain unchanged.
When to Use UPPERCASE
Use UPPERCASE for headings and titles to grab attention, acronyms and abbreviations (NASA, FBI, CEO), emphasis in informal writing, legal documents for names and important terms, warning messages and alerts, social media hashtags for visibility, constants in programming (MAX_SIZE, API_KEY), and shouting or strong emotion in digital communication.
