Frequently Asked Questions
Which case format should I use for JavaScript variables?
Use camelCase for variables and functions (e.g., userName, getUserData), and PascalCase for classes and constructors (e.g., UserModel).
What's the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (myVariable), while PascalCase starts with an uppercase letter (MyClass). Both capitalize subsequent words.
When should I use CONSTANT_CASE?
Use CONSTANT_CASE for values that never change, like API keys, configuration constants, and mathematical constants (e.g., API_BASE_URL, MAX_ATTEMPTS).
Is kebab-case the same as dash-case?
Yes, kebab-case and dash-case refer to the same format where words are separated by hyphens and all letters are lowercase.
