Snake Case vs. Camel Case: Have you ever wondered how choosing the right naming convention can impact code readability, maintainability, and even collaboration among developers? It’s a great question! Two popular naming conventions, snake and camel cases, have been widely adopted across various programming languages.
Snake Case vs. Camel Case
Snake case prioritizes readability and consistency with underscores, while camel case emphasizes conciseness with capitalized word boundaries.
But which one should you use for your projects? Let’s explore the differences between the snake and camel cases to help you make an informed decision.
Camel Case
Camel case, a simple yet effective naming convention, is where words are concatenated together, and the first letter of each subsequent word is capitalized. For instance, “FlywayMigrator” adheres to the camel case convention. This naming style is widely used in languages like Java and Kotlin, and its simplicity and effectiveness make it a breeze to adopt!

The advantage of the camel case lies in its readability and conciseness. Camel case identifiers are a great way to make your code easier to read and understand, especially for longer variable names or class names. They’re also great for acronyms! However, if you’re not used to them, they might take a little getting used to. Also, there might be better choices for complex or nested structures.
Snake Case
Snake case is a great way to make your code more readable. It’s a naming convention where words are separated by underscores. For example, “flyway_migrator” adheres to the snake case. Languages like Python conventionally use snake case for variable names, function names, and other identifiers.
Snake case offers clarity and consistency, particularly for multi-word identifiers. The underscores serve as natural separators between words, making distinguishing them at a glance easier. This convention also aligns well with Python’s “readability counts” philosophy, which is all about making code as clear and simple as possible.
However, snake case can lead to longer identifiers compared to camel case, which might affect how your code looks, especially in languages where brevity is valued. Additionally, the presence of underscores might slightly increase the cognitive load when reading or writing code. You can use our Snake Case converter tool to see some examples.
Choosing the Right Convention
There is no one-size-fits-all answer when it comes to snake case and camel case. The decision depends on factors such as the programming language, conventions, and personal preference.
If you’re working in Java or Kotlin, stick with the camel case for consistency and compatibility. If you’re coding in Python or another language that favors the snake case, adopt this convention for readability and maintainability.
Sometimes, the choice might also be influenced by the specific context of your project. For instance, if you’re developing an API where URLs need to be human-readable, snake case might be a better choice for endpoint names.
Is snake case better than camel case?
It’s totally up to you whether snake case is better than camel case! It all depends on the context of your project and your personal preference. Snake case, with its underscores as word separators, can really enhance readability, especially when dealing with longer identifiers or multi-word names.
It’s designed to mimic natural language conventions, making code easier to understand at a glance. On the other hand, camel case offers conciseness and a visually text style that some developers prefer. Ultimately, the best choice is to use the naming convention that aligns with your project’s requirements and coding standards. That way, you can be sure you’re making the right choice for your project!
Conclusion
Both snake case and camel case are great ways to name things in programming. They each have their own strengths and weaknesses, but they’re both useful! While camel case is great for making things concise and easy to read, snake case is great for making things clear and consistent.
The most important thing is to be consistent with how you name things in your codebase. Stick to the conventions your programming language or community has set up, and you’ll be fine! By choosing the right naming convention and sticking to it consistently, you can make your code easier to read, make collaboration a breeze, and ensure your projects are easy to maintain.
