Pascal Case vs. Camel Case: Know the Difference

Shumaila Saeed
By Shumaila Saeed || Published on February 22, 2024
Pascal Case capitalizes the first letter of each word (e.g., PascalCase); Camel Case capitalizes the first letter of each word except the first (e.g., camelCase).
Pascal Case vs. Camel Case

Key Differences

Pascal Case is a naming convention in which each word within a compound word begins with a capital letter, with no intervening spaces or punctuation. Camel Case, similarly, is a compound word format where the first word starts with a lowercase letter and subsequent words start with uppercase letters.

In Pascal Case, every word, including the first, is capitalized, making it common in certain programming contexts like class names in C# and Java. Camel Case, on the other hand, begins with a lowercase letter, making it a frequent choice for variable names in programming languages like JavaScript and Python.

Pascal Case provides a clear distinction at the start of each word, which can enhance readability in certain cases, such as in defining object-oriented programming constructs. Camel Case, while also enhancing readability, does so with a more subtle approach, emphasizing the start of new words from the second word onward.

The use of Pascal Case is often dictated by language-specific conventions or coding standards, especially in statically typed languages. Conversely, Camel Case is widely adopted in both statically and dynamically typed languages, often seen in scripting languages and APIs.

Pascal Case and Camel Case both improve the clarity and comprehension of compound words in code, but their usage varies depending on the programming context, with Pascal Case often signaling a more formal or structural element like a class or interface, while Camel Case typically indicates variables or functions.
