Go Programming language

Golang aka Go was developed by Google as an open-source procedural programming language in 2007. R Griesemer, Rob Pike & Ken Thompson are the brains behind Go programming language. It was launched in 2009. Go programmingsupports concurrent programming allowing multiple processes to run simultaneously. It is attained by using goroutines, channels and so on. 

Since its arrival, several popular applications have been developed using the Go programming language. These include Dropbox, Kubernetes, Docker, Openshift, Netflix, InfluxDB and even the language Go was written in Go.

The Story Behind Go Programming Language?

Griesemer, Pike & Thompson created Go by taking inspiration from other languages like Algol, C, Oberon, Pascal, Modula, Newsqueak & Smalltalk. Mostly, it was inherited from Oberon programming and C programming was responsible for its syntax.  OOP of Go programming is similar to Smalltalk, though you can attach methods to any type. While concurrency is based on Newsqueak, another language created by Rob Pike.

Despite having so many languages, why Google created Go language?

Every language has its own flaws along with its benefits. For instance, fast languages like C are not safe and are difficult to work on along with vast compiling speed, runtime errors and dependencies. When it comes to interpreted languages like Ruby, it might be safe but it is slower and has several dependencies including interpreter itself. On the other hand, programming languages like Java requires a virtual machine to run the code. JS or NodeJS are wild kids.

Considering all these drawbacks, Go was designed for fast compilation. Because of this, it’s hard for programmers to create compiling programs that are slow when compared to programming languages like C++ or C. Moreover, Golang combines the ease of programming of a dynamically, interpreted type language with the safety and efficiency of a compiled & statically typed language. It also has the capability of being modern and can support multicore computing.

What are the things of other programming languages that Go programming language lacks?

Throughout the design of Go programming, developers have tried to reduce clutter and complexity. It helps in reducing the amount of typing. However, you will not be able to find any forward declarations or header files, as everything is declared exactly once. There is not any type of hierarchy. Apart from some hardware limitations, sluttering is also reduced by simple type derivation using the := declare-and-initialize construct.

Exploring the Golang Advantages & Disadvantages

Recently, I used Go for one of my projects. It taught me a few things which I’ll state below. Before choosing any programming language, I believe that you should understand the real aim and requirements before starting. Some of the Golang pros & cons that I found out are:

Things that give Golang an edge:

benefits

1. It is fast:

Honestly, Go programming language is very fast mostly because it is compiled to machine code. Naturally, Golang outperforms other languages that have virtual runtimes or are interpreted. Also, you can compile Go programs very fast and API can be compiled in seconds, producing an executable file of over 11 MB. The resulting binary is very small too.

2. Very easy to learn:

When compared to other popular languages, the syntax of Go is very small and easy to learn. Because of this, you are not required to spend a lot of time looking for various things. This language is also very easy to learn and understand. For the non-Go programmers, reading a program written in Golang and understanding is not that hard, especially for those who are used to C-style syntax.

3. Static typing:

This programming language is a strongly, statically typed language. You can find primitive types like int, byte, and string along with structs. Just like any other strongly typed language, you can catch entire classes of bugs with the help of compiler, all thanks to its type system. It is also packed with built-in types for maps and lists that are easy to use.

4. Interface types:

Go includes interfaces that can be satisfied by any structs by implementing its methods. It will allow you to decouple the dependencies in your code. Afterward, you can even mock your dependencies in the test. The interface also allows you to write more testable and modular code. There is also the provision of first-class functions that opens up the possibility of writing your code having a more functional style. 

5. Standard library:

A nice standard library is provided for this programming language and is good for built-in functions for working with primitive types. With some of its packages, you can easily handle I/O, stand up a web server, manipulate raw bytes and work with cryptography. You can use tags to specify JSON field names just next to struct fields. 

6. Testing support:

It is built into its standard library and there is no need for an extra dependency. In the case, where you have a file having a name thing.go, you just have to write your tests in another file called thing_test.go to test it in Golang. This programming language has the capability to test these types of tests really fast.

7. Static analysis tools:

You can find numerous and robust static analysis tools for Golang. One of the most popular and useful ones is gofmt that can format your code as per Go’s suggested style. It can help your team to focus more on the code by normalizing a lot of opinions on a project. I tried golint, gofmt and vet in almost every build and the build fails in case of any warnings came.

8. Garbage collection:

Intentionally, memory management in Golang was made easier than other popular programming languages like C or C++. Dynamically allocated objects are garbage collected & with Golang, you can use pointers much safer because it doesn’t allow pointer arithmetic. You also have the option of using value types.

9. Easier concurrency model:

The majority of programmers know the fact that concurrent programming is not easy, but Golang makes it very easier for all the programmers. You can create a lightweight thread known as “goroutine”, and communicate with it via a “channel”.

Things that were missing in Golang:

1. No generics:

Yes, Golang doesn’t have generics and it is a big hurdle for you if you are more into languages like Java. This decreases the level of reuse in the code. For instance, if you write functions like “reduce”, “map”, or “filter” that generally operates on a collection of a type, you can’t reuse those same functions for a collection of any other type. Though there are several ways to deal with this, but eventually you will end up writing more codes. It ultimately affects your productivity and maintainability.

2. Interfaces are implicit:

Yes, having interfaces are great for any developers but in this language, structs can implement interface implicitly but not explicitly. Many might consider it as strength of this programming language, however, for me, it was difficult to tell from looking at a struct whether it implemented an interface or not. The only way you can find out this is by attempting to compile the program. For many programmers, it is not a big task if the file is small but it becomes a hectic task when your file is of large or even medium size.

3. Poor library support:

You read correctly; the library support for Golang is very poor. You are required to write and maintain a ton of code to request and parse data from Contentful. You might even have to look for a third-party Elasticsearch library. SDKs for Go provided by its developers are not that loved by the developers as much as other programming languages like Ruby, Java or JavaScript. 

4. Difficult community:

The community behind Golang seems non-receptive. As I found out that there was an issue in the GitHub repository where a user has requested the ability for golint to fail a build when there are warnings found. It was immediately dismissed by the maintainer and when some more people commented on the same issue, the maintainer added the requested feature almost a year later. Moreover, Git also seems a strong dislike from the Go community towards web frameworks. There are hundreds of developers who are now avoiding to use the frameworks as it’s practically impossible for them to choose any framework that will not be abandoned after you have started your project.

Summing Up Golang Programming Language!

Conclusion

So this is it. This is Golang, an open-source procedural programming language created by Google to counter the problems faced by other popular programming languages such as C, C++, Java, Ruby, JavaScript, and others. Though it might provide a great solution for security, speed, runtime errors, and others, but even Go programming language has its own set of flaws. 

I will simply suggest that before choosing Go programming or any other programming language, you should first be clear about the aim of your projects, its outcomes, and the desired output. If these three are covered by Golang then you should definitely use it. And if you are new to it then it will not be very difficult to learn Golang. If you are looking for the Golang installation instructions then that is also mentioned above.

Lastly, if you are new to Go programming but you are sure that you have to use it then you can check out the lists of top Golang IDEs & Code Editors that developers are using in 2020. And if you think we have missed something then do mention it in the comment section below.
