Go Language Tutorial

Go is an open-source programming language aimed at being simple, dependable, and efficient.

In 2007, Google created the Go programming language. Google was developing significantly at the time, and the code used to manage its infrastructure was expanding in both size and complexity. This huge and sophisticated codebase began to slow down certain Google cloud engineers. As a result, they decided that a new programming language with a focus on simplicity and speed was required. Go was created by Robert Griesemer, Rob Pike, and Ken Thompson.

In 2012, Go became an open-source project and was made publicly available. It grew in popularity quickly and is now one of the most widely used modern programming languages.

What is the purpose of Golang?

Go was designed specifically for networking and infrastructure applications. It was designed to take the place of popular server-side languages like Java and C++. Go is now utilised in a wide range of applications:

  • Go is widely used in cloud and server-side applications.
  • Go is also widely used in DevOps and site reliability automation.
  • Go is used to write a lot of command-line utilities.
  • In the fields of artificial intelligence and data science, Go is employed.

Go is used in microcontroller programming, robotics, and video games by some.

When it comes to infrastructure, though, Go really shines. Today’s most popular infrastructure tools, such as Kubernetes, Docker, and Prometheus, are developed in Go.

What makes Go so popular?

There are probably as many viewpoints on this as there are Go programmers, but two stand out:

The simplicity of programming language

To begin with, Go is easy to learn and comprehend. The Go spec may be read and digested in an afternoon, according to popular belief. Many developers who have tried Go say that it is simple to learn compared to other programming languages.

High-performance software

Second, Go is a high-performance language. Because language was created for large-scale automation, Go makes writing high-performance apps very simple.

Go vs Other Programming Languages

Go is one of the most popular languages among developers, according to the 2020 Stack Overflow Developer Survey. Go users appear to agree, with a 92 percent satisfaction rating in the 2020 developer poll.

Go vs Python

Python is more than 30 years old, but its popularity continues to rise. The language’s design has endured the test of time (despite some rough spots along the way). Python and Go are two of the most popular and user-friendly programming languages available today.

Python is an excellent object-oriented language, but you can also use it to construct functional programmes. Python is perhaps the programming language used by the most non-programmers of all the languages. One of the reasons Python is so popular is because of its versatility. It can be used for a variety of tasks, including file cleanup, web applications, server less projects, teaching programming to children, and animation.

But how does Go stack up against Python?

  • Python and Go both have a straightforward syntax and are supported by all major cloud providers as first-party languages.
  • Both Go and Python are simple to learn and straightforward to get started with for beginners. Which is easier is a point of contention. Go is a simpler language that can be learned faster, but some people find it more difficult to get started than Python, which takes longer to master because there is more to understand.
  • In comparison to Python, Go is a relatively new language that was created with speed in mind. Python is slower than Go. Much slower.
  • Python is popular in data science, while Go is ideal for system programming.
  • Python has a larger library and community because it is the more senior language.
  • Python’s dynamic typing makes it a better choice for rapid prototyping than Go.
  • Go makes it possible to run apps at scale. Go was created by Google to solve challenges on a Google-sized scale, making it perfect for big concurrent applications. Concurrency, or the ability to perform many programs/tasks at the same time, is supported in Go. Python isn’t one of them.

Python and Go each have their own set of advantages, but there’s no reason you can’t learn to use both!

Advantages and Disadvantages of Go Language


  • It is adaptable because it is succinct, straightforward, and simple to read.
  • Concurrency allows several processes to execute at the same time and efficiently.
  • Its compilation time is quite short.
  • It comes with a large standard library.
  • Garbage collection is an important aspect of go. Go excels at giving you a lot of control over memory allocation, and the garbage collector in recent versions has substantially decreased latency.
  • It checks for type embedding and interface validation.


It does not support generics, despite numerous discussions on the subject.

Although the Go programming language comes with a number of useful packages, it is not object-oriented in the traditional sense.

Some libraries, particularly a UI toolkit, are missing.

Should I start learning Go?

So, what are the benefits of learning Go? It’s simple to play. Many programmers agree that Go is simple to learn. Its code is also quite simple to comprehend. Learning Go will provide you with a lot of power and variety.

  • Go is a versatile language that can handle everything from infrastructure to web development to data processing.
  • Go is popular on cloud systems. Go is supported as a significant language by Amazon Web Services, Microsoft Azure, and Google Cloud Platform (GCP). As a result, Go is an excellent choice for cloud development.
  • Go also has a thriving open-source community that creates modules and libraries, assists newbies, and contributes to the Go project itself.
  • Go engineers earn the second-highest median wage in the United States, at $140,000 per year, according to the 2020 Stack Overflow Developer Survey.

Check out Go if you’re looking for a programming language that can do a lot, has a fantastic community, and is simple to learn.
