Standard library of Go contains a ton of great handy features, which proves that Golang is, in fact, a pretty feature-rich language. However, the way they are implemented is something that makes it so unique. For instance, with the use ofimport “net/http' magic package, you’re at once getting all of the above features implemented in an awesome, highly concurrent, crazy easy to use, through a fully production-ready web-server.

Interfaces are clearly one of Golang’s most distinct and recognizable features. Their unique design solution addresses most of OOP criticism on its own, enables orthogonality and true component architectures while being just a valueless set of methods, which still hides few ingenious design tricks.

Having vendoring (replaced by Go Modules since 1.11), a robust dependency-management system, and its assembler being extremely close to binary code in order to achieve blazing fast builds and afterward be very lightweight and binaries size-efficient. That makes it a perfect match for the microservice architecture pattern and for cloud-native development in general.

As seen, Go’s developers have managed to come up with a greatly efficient system of language-based constraints to achieve some of its greatest characteristics and features. This practice is very impressive in such a way that by using every single constraint, it manages to simultaneously achieve not one but multiple major features at once.

Not having a try-catch exception handling. Despite being very controversial and criticized, this is in fact Golang’s really idiomatic way of dealing with errors, which is actually beneficial in many ways: avoiding repetitive error-handling code, keeping control flow efficient and execution fast, keeping code clean and readable, and simplifying code writing and debugging.

“Go is actually complex. It is, in fact, one of the most complicated things I ever worked on, and yet, it feels simple … It requires a lot of design, thinking, implementation work, refinement. Simplicity is the art of hiding complexity!”— Rob Pike, creator of Golang

However, that does not necessarily mean that Go is deficient or missing some important functional features. This would, in fact, make programming useless, since why not use an assembly language in the first place. But this isn’t the case with Go. It surely has some features. The thing is, though, that in order to stay simple, Go is very deliberate about not having features that bring more complexity without solving the problem. This is, in fact, one of those things that makes Go “idiomatic,” as it famously used to be called.

Concurrency aka Goroutines is generally known to be the easiest and most straightforward implementation of the concurrency model so far. The process of spawning a new subprocess is, in fact, so simple that it feels more like doing nothing at all. All you need to do is just type go. It just can’t get easier than that, right?

Garbage collector is, in fact, the most simple feature of Go, since it doesn’t have any control interface. Yet also it is reasonably its most complex one because it manages to provide complete memory safety while saving an exceedingly high runtime speed and providing surprising resource efficiency. Bravo to the creators!

“Many newcomers to Go ask for features from languages they know. But those features do not belong in Go — and the language is fixed. Adding features to Go would not make it better, just bigger. That would make Go less interesting by being less different.” — Rob Pike, creator of Golang

Packages. Simply put, they are just awesome. They work seamlessly, without any surprises, and it feels great to use them, too, especially to import ones. By using the go get tool, you can do it from just about anywhere: Gopkg, GitHub, GitLab, BitBucket, even your own hosted repository source since “vanity” imports was introduced. But I guess, you already know the drill … Yep, they are secretly also pretty complicated in order to enable componentization, modularity, scalability, sharing, data hiding, and isolation, and so on.

Also, at this point, it becomes clear that Go is, in fact, unlike other languages, since they are evolving commonly by adding new features, thereafter growing their complexity and becoming convergent. Whereas Go uses an approach to constrain itself in the first place and then stays mostly finite from its very beginning.

Yes, by all means, Go isn’t the fastest programming language, since we have Rust, Julia, C , and C for sure. But none of these languages have GC and therefore aren’t even close to being as simple as Go — and it isn’t that slow, actually. In most cases, though, this is possible also due to the next exceptionally simple feature.

So what about features that have managed to become a part of Go? Well actually, the rule of intentional simplicity is very much acting for them too. And by saying that, I mean that Golang’s creators have done an incredible job of creating what seems to be something so simple and easy to use, while under the hood is actually highly complicated.
