Pascal Case Vs Camelcase

Pascal Case Vs Camelcase: Understanding When to Use Which One

In the world of programming and software development, the use of proper naming conventions is crucial for ensuring that your code is readable, maintainable, and easy to understand. Two popular naming conventions that are often used are Pascal Case and Camelcase. But what are they, and when should you use one over the other? We will delve into these questions in this article, and provide you with a better understanding of which one to use and when.

What is Pascal Case?

Pascal Case is a naming convention in which the first letter of each word in a phrase or compound word is capitalized. The convention is named after Blaise Pascal, the French mathematician, and philosopher, who was famous for his contributions to the fields of probability theory and computer science.

Some examples of Pascal Case include:

• UnitedStates
• FirstName
• MaximumValue

As you can see, all the words in the phrase are capitalized, starting with the first one, except for the first letter of the first word in the phrase.

When to Use Pascal Case?

One of the primary advantages of Pascal Case is that it can help you make your code more readable and easy to understand. This naming convention is particularly useful when you’re working with long variable names, class names, or method names, as it breaks them down into smaller, more manageable chunks.

Here are some instances when it’s recommended to use Pascal Case:

1. When you are defining a class name or an interface name, Pascal Case is the standard naming convention. For example, if you are defining a class called “Product,” it should be written as Product, with the first letter of each word capitalized.

2. When creating a method name, it’s advisable to use Pascal Case, as it makes the method name more readable and understandable. An example of a method name in Pascal Case would be “GetProductById.”

3. When creating a variable name, using Pascal Case, the first letter of each word is capitalized, makes the code more organized and helps you understand the variable’s purpose. For example, “TotalNumberOfProducts.”

What is CamelCase?

Camelcase is a naming convention where the first letter of the first word is in lowercase, and the first letter of each subsequent word is capitalized. The name Camelcase comes from the way the words are displayed, as the pattern mimics the humps on a camel’s back.

Some examples of Camelcase include:

• firstName
• maximumValue
• totalNumberOfProducts

When to use Camelcase?

Camelcase is also a useful naming convention when working with code. Here are some instances when you should go for Camelcase:

1. When you’re working with JavaScript, or other programming languages, that require object properties containing multiple words. In this case, it’s recommended to use Camelcase for property names. For example, “firstName” can be used as a property in JavaScript.

2. When working with API endpoints, it’s recommended to use Camelcase. By using this convention, the API endpoints become more readable and easier to understand.

3. When working with files or folders in your project, it’s advisable to use Camelcase for the file and folder names. This helps to differentiate between the formats and folder types and makes for easy identification.

Which One Should You Use?

The choice of which naming convention to use depends on your project’s requirements, your personal preferences, and the programming language you’re using. Typically, different languages have different standards, and it’s essential to follow them.

If you’re working in C#, Pascal Case is the standard naming convention. On the other hand, if you’re working in JavaScript, Camelcase is the most commonly used naming convention for JavaScript properties and methods.


Proper naming conventions are essential when working with code as it makes the code more readable, maintainable, and easier to understand. Pascal Case and Camelcase are two popular naming conventions widely used in the tech industry. You should use Pascal Case when working with long variable names, class names, or method names, while Camelcase is best for use in JavaScript properties, files, folders, and API endpoints. You need to choose the naming convention that best suits your needs, personal preferences, and projects’ requirements. By following the correct conventions, you will prevent misunderstandings and ensure that your code is consistent and easy to read.
