What is UPPERCASE?

Uppercase text (also known as capital letters or majuscule) is when every letter in a string is capitalised. It is commonly used for headings, acronyms, emphasis, and formal titles. In programming, uppercase is often used for constant variable names.

When to use UPPERCASE

Use uppercase for headings and titles that need strong visual impact, for acronyms and abbreviations (NASA, HTML, UK), for constant names in code (MAX_VALUE, API_KEY), and when you need to draw attention to important text such as warnings or legal notices.
