Pascal case and camel case are two popular naming conventions used in programming. Both conventions are used to describe the way words in a sentence are capitalized when they are used together to create a variable name or function name.
While even those without programming experience can recognize the differences in capitalization between the two conventions, there are many differences between the two that a programmer might consider when choosing between the two.
What is Pascal Case?
Pascal Case, also sometimes referred to as Upper Camel Case, capitalizes the first letter of each word in the sentence, including the first word. For example, variables or functions may be named like this: ThisIsUpperCamelCase.
Pascal Case is commonly used in languages such as Java and C#, and at the beginning of an identifier. This is because the first letter of the identifier is important to differentiate it from other types of variables.
What is Camel Case?
Camel Case, also called Lower Camel Case, capitalizes the first letter of each word in the sentence, except the first word. For example, variables or functions may be named like this: thisIsLowerCamelCase.
Camel Case Vs. Pascal Case
The two conventions have several differences in appearance and usage, but the following will present the main differences between the two conventions.
Pascal Case names are more readable than Camel Case names, especially when used in large files. Although Camel Case is easier to type and less verbose, it can be difficult to read and understand when used in long, complex sentences.
Pascal Case capitalized the first letter of each word in a sentence, while Camel Case only capitalizes the first letter of each word after the first word in the sentence. Pascal Case also always capitalizes the first letter of the entire word, while Camel Case only capitalizes the first letter of the first word in the sentence.
4. Naming Conventions
Programming languages like Java and C# are rooted in Object-Oriented Programming, which is based on classes and objects. The naming conventions and syntax conventions of Camel Case and Pascal Case emphasize this. For instance, many Object-Oriented Programming languages use Pascal Case for class names, and Camel Case for variable names.
In Summary, Pascal Case Versus Camel Case
The choice between Pascal Case and Camel Case naming conventions primarily depends on the individual’s coding environment, coding language, and coding standards. Pascal Case is ideal for coding environments that prioritize readability, while Camel Case is best suited for coding environments that prioritize speed and conciseness.
Q. When should you use Pascal Case?
A. Pascal Case is best used when naming classes, constants, or global variables. In Pascal Case, the first letter of every word is capitalized, which makes it ideal for highlighting the importance of the first letter, as is the case with classes, constants, or global variables.
Q. Why use Camel Case?
A. Camel Case is best suited for naming variables or functions that are local to a coding environment. The fewer characters in the variable or function name, the faster it is to type. Camel Case also makes code easier to read and write, which makes it ideal for coding in environments with limited space.
Q. Can you mix Pascal Case and Camel Case?
A. Yes, you can mix Pascal Case and Camel Case. However, it is important to apply the correct convention to the correct type of variable or function within your code. Mixing the two conventions can introduce confusion to your code, especially if the code is shared with others.
Pascal Case and Camel Case are two popular naming conventions used by programmers to create variable or function names. Both conventions have their advantages and disadvantages, and choosing the right convention depends on the specific programming language and the context.
Pascal Case is best suited for naming classes and global variables, while Camel Case is ideal for local variable and function names. Ultimately, the final choice of naming convention rests with the individual programmer or coding team, considering the coding standards, best practices and programming language used.
