KebabCase vs SnakeCase vs CamelCase vs PascalCase

Differences Between Camel Case, Pascal Case, Kebab Case, and Snake Case

When naming variables, functions, or files in programming, developers follow different naming conventions depending on the language, framework, or style guide they adhere to. The four most common naming conventions are Camel Case, Pascal Case, Kebab Case, and Snake Case. Here’s how they differ:

1. Camel Case (`camelCase`)
✅ Example: `myVariableName`, `getUserData`, `fetchAllRecords`

Definition: In Camel Case, words are joined without spaces, and each word after the first is capitalized.
Usage: Common in JavaScript, Java, and C# for variable names, function names, and object properties.
Example in JavaScript:

let userProfileData = {};
function fetchUserDetails() {}


Why use it? It improves readability while keeping names concise.
2. Pascal Case (`PascalCase`)
✅ Example: `MyVariableName`, `GetUserData`, `FetchAllRecords`

Definition: Similar to Camel Case, but the first letter is also capitalized.
Usage: Common in C#, Java, and TypeScript for class names, constructors, and public methods.
Example in C#:

public class UserProfile {}
public void GetUserDetails() {}


Why use it? It visually distinguishes class names from variables.
3. Kebab Case (`kebab-case`)
✅ Example: `my-variable-name`, `get-user-data`, `fetch-all-records`

Definition: Words are lowercase and separated by hyphens (-).
Usage: Common in URLs, CSS class names, and file names.
Example in CSS:

.user-profile-container {
background-color: #f0f0f0;
}


Why use it? Hyphens are easy to read and widely supported in web development.
4. Snake Case (`snake_case`)
✅ Example: `my_variable_name`, `get_user_data`, `fetch_all_records`

Definition: Words are lowercase and separated by underscores (_)
Usage: Common in Python variables, SQL column names, and some config files.
Example in Python:

user_profile_data = {}
def fetch_user_details():
pass


Why use it? It improves readability in environments where spaces aren't allowed.
Quick Summary:
| Naming Style | Example | Used In |
|--|--|--|
| Camel Case | `myVariableName` | JavaScript, Java, C# (variables & functions) |
| Pascal Case | `MyVariableName` | C#, Java, TypeScript (classes & constructors) |
| Kebab Case | `my-variable-name` | CSS, URLs, file names |
| Snake Case | `my_variable_name` | Python, SQL, configuration files |

Each style has its best use case, so choosing the right one depends on the programming language, environment, and coding style guidelines.
