Why Go Should Sometimes Be a No-Go?

The Go language was criticized for its simplicity and design philosophy in a recent article called “Why Go Should Sometimes Be a No-Go”, where the author raises some negative points about the language, arguing that its minimalist approach can be a limitation in certain contexts. However, these arguments can be countered with a broader view of Go’s benefits and purposes.

1. Is Go boring? Efficiency above all

The article argues that Go is “boring” because it does not offer constructs like map, filter, and reduce, requiring developers to implement these operations manually with loops. However, this design choice is not a flaw, but a conscious decision to keep code readable and predictable.

By avoiding excessive abstractions, Go makes code maintenance and debugging easier. In many languages, heavy use of functional constructs can make it difficult for new developers to quickly understand legacy code. In addition, by forcing a more explicit approach, Go reduces cognitive complexity and minimizes unexpected errors caused by implicit behavior in complex functions.

Another relevant point is that, in high-performance systems and distributed applications, explicit loops often outperform approaches based on higher-order functions in terms of efficiency, since they avoid unnecessary memory allocation and overhead related to excessive abstraction.

2. Does Go discourage Clean Code principles? In fact, it reinforces them

Go’s simplicity encourages clear and direct development practices. Instead of allowing multiple ways to solve the same problem, Go imposes standardization that reduces complexity and facilitates team collaboration. The focus on explicit code avoids excessive use of unnecessary abstractions, making the code more understandable for all members of a team.

By adopting strict conventions, such as automatic formatting by gofmt, Go removes discussions about style and formatting, allowing developers to focus on what really matters: the program logic. In addition, the absence of exceptions (replaced by explicit error handling) forces developers to handle failures in a structured way, making systems more robust and predictable.

3. Is Go small and does it force the Do It Yourself philosophy? Modularity is a benefit

The article mentions that external libraries are widely used to supply features that the language does not offer natively. This argument suggests that Go is “incomplete”, but the reality is that this modularity is an advantage.

Go’s philosophy follows the UNIX principle: “do one thing and do it well”. Instead of bloating the language with features that not every project needs, Go allows developers to choose external tools as needed. This gives freedom to adapt the language to different contexts without overloading its core.

Instead of forcing all developers to carry a large number of built-in language resources, Go allows a lean and efficient ecosystem, where external packages can be used according to the specific needs of the project. This model keeps the language base lightweight and optimized, enabling better performance and shorter compilation times.

4. In Go, is there only one way to do things? And is that bad?

The existence of a single way to solve common problems avoids unnecessary debates and simplifies code reading and maintenance. This does not mean a lack of flexibility, but rather a pragmatic design that prioritizes efficiency. Many languages that offer multiple ways to perform the same task end up generating inconsistent code that is difficult to standardize within a team.

In addition, the predictability of Go code reduces the learning curve for new developers, allowing teams to expand their workforce more efficiently. Code written by one engineer can be quickly understood and maintained by another, without the need to navigate multiple implementation approaches.

Another benefit is that, by restricting the language to an essential set of constructs, Go makes optimization and static code analysis easier, enabling better software engineering practices and greater control over application performance.

5. Is debugging in Go not fun? Modern tools help

Although Go’s native debugger was basic in the past, today there are advanced tools such as Delve, which offer a powerful environment for debugging. In addition, the language’s own simplicity reduces the need for intensive debugging, because errors tend to be more obvious and easier to trace.

Go’s explicit error handling model also helps avoid silent problems. Because developers need to handle errors directly, failures are less likely to go unnoticed, reducing the need for deep debugging. In addition, the combination of panic/recover and built-in profiling in the language offers effective mechanisms for failure analysis and performance optimization.

Another important point is that Go’s fast compilation and static typing help identify errors before execution, minimizing the incidence of runtime failures and reducing the need for extensive debugging.

Go is not perfect for every scenario, just like any language. However, its characteristics - simplicity, stability, and modularity - make it a strategic choice for many projects, especially those that value performance, scalability, and ease of maintenance. What may seem like a limitation at first often translates into long-term benefits.

Go’s philosophy prioritizes efficiency, clarity, and predictability, eliminating unnecessary complexity and ensuring a productive and reliable development environment. Although some language decisions may seem rigid, they promote good software engineering practices and result in more robust, easier-to-maintain systems.
