Why Isexist Not Doesexist Golang

Go Programming

In the world of Golang, one of the common questions that often arises is why there is no isexist keyword but instead doesexist. As a Golang enthusiast and developer, I’ve encountered this question multiple times, and I understand how confusing it can be for newcomers. Let’s delve into this topic and explore the reasoning behind this design choice.

Understanding Golang’s Naming Conventions

Golang, also known as Go, is known for its simplicity and readability. It follows a set of naming conventions and idiomatic patterns that aim to make the code clean and understandable. In Golang, the use of descriptive names for functions, methods, and variables is highly encouraged.

When it comes to the difference between isexist and doesexist, it all boils down to the emphasis on clarity and expressiveness. The Golang design philosophy favors explicitness and unambiguous naming, even if it means using slightly longer names.

The Choice of “doesexist” Over “isexist”

The decision to use doesexist instead of isexist is rooted in the desire for clear and unambiguous naming. The prefix “does” in doesexist serves as a more explicit indicator of action, as opposed to the state or condition indicated by “is” in isexist.

By using doesexist, the emphasis is placed on the act of checking for existence, making the code more expressive and leaving no room for misinterpretation. This aligns with Golang’s principle of favoring clarity and explicitness over brevity.

Personal Reflection

As a developer who appreciates understandable and maintainable code, I initially found the choice of doesexist a bit unusual. Coming from other programming languages, I was accustomed to seeing isexist or similar constructs. However, as I immersed myself deeper into Golang’s principles, I began to appreciate the rationale behind this decision.

Using doesexist not only enforces explicitness but also promotes consistency in naming conventions throughout Golang codebases. It fosters a standard that can benefit both individual developers and collaborative projects, leading to code that is easier to comprehend and maintain in the long run.


In conclusion, the use of doesexist over isexist in Golang stems from the language’s commitment to clear, explicit, and consistent naming conventions. While it may seem unconventional at first, embracing this approach ultimately contributes to the overall readability and maintainability of Golang code. As I continue my journey with Golang, I’ve come to appreciate and adhere to these principles, valuing the clarity they bring to my code.
