Question 1

What is camelCase and when is it used?

Accepted Answer

camelCase starts with a lowercase letter and capitalises the first letter of each subsequent word — for example, firstName or getUserById. It is the standard for JavaScript variable names, function names, and JSON property keys in most style guides.

Question 2

What is the difference between snake_case and kebab-case?

Accepted Answer

snake_case uses underscores between words (user_first_name) and is standard in Python, Ruby, SQL column names, and environment variables. kebab-case uses hyphens (user-first-name) and is used in CSS class names, HTML attributes, URL slugs, and some CLI flags. Neither allows spaces — both are lowercase by convention.

Question 3

What is PascalCase used for?

Accepted Answer

PascalCase capitalises the first letter of every word including the first — UserProfile, HttpRequest. It is the standard naming convention for class names in Java, C#, TypeScript, and Python; React component names; and .NET namespaces.

Question 4

What is SCREAMING_SNAKE_CASE?

Accepted Answer

SCREAMING_SNAKE_CASE (also called CONSTANT_CASE or UPPER_SNAKE_CASE) is snake_case with all letters uppercase — MAX_RETRY_COUNT, DATABASE_URL. It is the standard for constants and environment variables in most languages.
