Camelcase Vs Pascal Case

When it comes to programming languages, capitalization plays a huge role. Not only does it make code more readable and organized, it also tells other programmers what a particular variable, function, or class is doing. There are two main ways to capitalize code: CamelCase and PascalCase. In this article, we’ll explore the differences between CamelCase and PascalCase and which one is better suited for various programming languages.

What is CamelCase?

CamelCase is a convention where the first letter of the first word in a phrase is in lower case and the first letter of every subsequent word is in uppercase. CamelCase is often used in programming languages such as Java, Python, and Ruby. The name “Camel” comes from the hump-like appearance of the capital letters resembling the humps on a camel’s back. Here are a few examples of CamelCase:


What is PascalCase?

PascalCase, also known as UpperCamelCase, is a convention where the first letter of every word in a phrase is capitalized. It is often used in programming languages such as C#, JavaScript, and Objective-C. The name “Pascal” comes from the Pascal programming language, which was one of the first languages to use this convention. Here are a few examples of PascalCase:


CamelCase vs PascalCase: Which One should you use?

When it comes to choosing between CamelCase and PascalCase, it all depends on the specific programming language, the syntax and style guidelines, and the personal preference or team convention. Follow the guidelines set by the programming language or framework you’re using; for instance, the .NET Framework and C# use PascalCase, while jQuery and JavaScript use CamelCase. Here are a few factors to consider when choosing between CamelCase or PascalCase:

1. Consistency and Readability:
Regardless of which one you choose, the most important thing is to be consistent. If your codebase has a mix of both CamelCase and PascalCase, it will difficult to read and prone to confusion. Choose one convention and stick with it to ensure readability and maintainability.

2. Programming Language and Framework:
Different programming languages and frameworks have different conventions and syntax requirements. Ensure that you follow the correct convention for the language being used. For instance, in C#, PascalCase is used for class names and method names, while CamelCase is used for variable and method parameters.

3. Personal Preference and Team Convention:
If a project doesn’t have a guideline to follow or a team convention, the choice between CamelCase and PascalCase is up to personal preference. Some people prefer CamelCase because they find it quicker and more natural to type, while others prefer PascalCase because it’s more consistent and traditional. Some teams may use CamelCase for properties, and PascalCase for function and class names. Choose the one that suits you and your team, and be consistent with its usage.

Frequently Asked Questions (FAQs):

1. Which programming languages use CamelCase?

Languages such as Python, Ruby, and Java often use CamelCase conventions.

2. Which programming languages use PascalCase?

Languages such as C#, Objective-C, and JavaScript (JQuery) use PascalCase conventions.

3. Why use PascalCase over CamelCase?

PascalCase is more consistent and traditional, and can help to distinguish between different types of objects in your code.

4. Why use CamelCase over PascalCase?

CamelCase can make your code easier to read, and can help to save typing time.

5. How do I choose between CamelCase and PascalCase?

Consider factors such as consistency, programming language and framework conventions, and personal preference or team conventions. Choose one convention and stick with it for readability and maintainability.


Capitalization plays a significant role in programming languages, affecting readability and organization. The two main conventions used are CamelCase and PascalCase, each with its own advantages and disadvantages. Choosing the right convention depends on the specific programming language, personal preference, and team conventions. No matter which one you choose, consistency is critical for maintainability and readability.
