❓ Frequently Asked Questions
What is camelCase used for?
camelCase is commonly used in programming for variable and function names, especially in JavaScript, Java, and Swift.

PascalCase capitalizes the first letter (HelloWorld), while camelCase doesn't (helloWorld). PascalCase is used for class names.
