What is lowercase?
Lowercase, also known as small letters or minuscule, is a text format where all letters are in their smaller form. This is the most common format for body text in most languages.
When to Use lowercase
- Body text: The standard for most written content
- URLs and domains: example.com, mywebsite.org
- Email addresses: user@example.com
- File names: document.pdf, image.jpg
- CSS classes: .button-primary, .nav-item
- Variable names: username, totalCount
Examples
Input: Welcome To Our WEBSITE
Output: welcome to our website
Programming Example:
const username = "johndoe";Common Use Cases
Web Development
URLs, CSS class names, and HTML attributes are typically lowercase for consistency and to avoid case-sensitivity issues.
Email Addresses
While technically case-insensitive, email addresses are conventionally written in lowercase.
Programming
Many programming languages use lowercase for variable names, function names, and package names.
