Golang Programming Language

Developed by Google, Go is a programming language that slowly and steadily won the trust of the software development industry. And for all good reasons. Due to the increasing prominence of microservice architecture, a large number of big brands have adopted it and now it is the new sensation in the Mobile App Development world.

Big brands like Netflix, Uber, Slack, and many others use Go in their technology stack and for various purposes. Undoubtedly, the traction “Go” has at present is worth it. No doubt why it is the third most popular language among developers on GitHub in terms of stars.

Why Golang is so popular


While Go is a language much similar to C, it also offers what C lacked, for example, garbage collection, memory safety, structural typing, and CSP-Style concurrency. This is another reason why it is considered one of the best programming languages for the coming years.

Furthermore, Go just did not get traction recently and immediately. It has been the favorite tool of developers for many years now. According to a StackOverflow 2020 Survey, Go was one of the most loved and wanted programming languages of developers. Its capabilities are tried, tested, and well-recognized by industry-leading experts.

Most Popular Programming Languages

Now, you must be wondering what made it compete with classic and well-established mobile app development languages like Java, C++, Python, and PHP. All the above, what can you achieve with it? Well, the answer lies in its amazing features and incredible capabilities. In this article, we are going to discuss all of them. So, let’s get started.

The Early Days of Google’s Golang

The Golang programming language was invented in 2007 by three Google engineers – Robert Griesemer, Ken Thompson, and Rob Pike. Their focus was to resolve challenges that developers face while using other system languages and create a language with all the characteristics of famous languages. That is the reason why Golang’s:

  • Syntax is very similar to C
  • It has easy code readability like Python
  • It handles parallelisms like Java
  • It has the readability and usability of JavaScript
  • Runtime efficiency of C++

Golang is also the best and latest programming language with multi-threading at its core. It has been proven many times that apps built using Golang are highly scalable and robust. No doubt why BBC uses it for the backend, Soundcloud uses it for the build and deployment system, and Uber for increasing its app’s latency, uptime, and performance.

Now, the question is, is Golang really worth using for your business app idea? What makes it better than classic programming languages like Objective C, Swift, Java, and Kotlin? Let’s put some spotlight on its benefits, features, and use cases to find out an answer.

Should You “Go” or Not: What’s So Special About Golang?

Being a statically typed and compiled language, Go is much faster than other programming languages and also offers many performance benefits. Here are some of the reasons why you should go with Go:

Business Benefits of Golang

1. Speed

Go is a compiled language. Thus, unlike interpreted languages, Go can directly translate to machine code before even execution. That means more efficient, simple, and faster code.

Effective garbage collectors and static types in Go also make it faster as compared to other high-level languages for app development. Even when you compare Go with Java, which is known to be one of the most penultimate languages, Go wins on the speed benchmark.

2. Scalability

Golang is an open-source programming language. Thus it is not new to the modifications and tools that increase its usefulness. For example, you can find many plugins in Golang’s GitHub repository to enhance your app functionality. Some of the tools that are very popular include:

  • Revive: It extends the framework for the creation of custom rules in Go.
  • Gotests: It offers an easy way to generate table-driven tests using core logic.

3. Convenience

Go is always compared with scripting languages like Python to fulfill the needs of developers. Some of its features are already built in Golang, such as Goroutines for threadlike behavior and concurrency. You can easily find other capabilities in the Go standard library package.

In addition, Go follows a test-as-you-go structure. Because testing is integrated into the toolchain, you can find and solve issues before it impacts other workstreams. This feature adds convenience and also increases the maintainability of the applications.

4. Support

Developed and maintained by Google, Golang has a huge community supporting it. So, you never have to worry if you ever face a problem with the Go code. There will always be expert Go developers around.

You can create Golang apps on Windows, Mac, and Linux. In addition, there are many IDEs and editors that support Go code, for example:

  • Vim
  • Atom
  • Sublime
  • Emacs
  • VSCode
  • Eclipse
  • IntelliJ

In addition, Golang is backward compatible, which means you can add new fixes to the older code without breaking or slowing it down. The feature also increases the security and reliability of the application. Here are some other Features of Golang that make it special:

  • Go is a compiled and statically typed language that allows developers to find and solve issues early on
  • Go is developed in a way that makes it easy for developers to write highly networked and concurrent programs
  • Go makes porting code seamless because of its cross-platform hallmarks – one of its best advantages
  • Go natively supports parallelism and concurrency and that makes it a perfect technology for apps that need networking, parallel processing, massive computing, etc.
  • It complies fast with machine code and that makes app updates fast and produces efficient machine code
  • It has a lot of built-in infrastructures. For example, it supports a test-as-you-go model that lets you define and test modules easily
  • Golang has features like fast compile times, automatic variable declaration, and garbage collection which is latency-free. Thus, it saves developers from manual memory management.

So that was all about Golang’s benefits and features. The language is the brainchild of Google and it surely has an edge over the competitors in the market. Let’s check out what type of apps can be developed using this incredible programming language.

Go Use Cases: What Type of Solutions Can Be Developed Using Golang?

Every technology has some special use cases. While Go was particularly developed for cloud-based apps, it can be used for many purposes, including:

Golang Use Cases

1. Cloud-Native Apps

Cloud computing is an essential element of modern software architecture. Using cloud services, one can easily create software systems that are highly shareable and scalable. Go is the best programming language to develop microservices and cloud-native software.

Its networking features, concurrency, and high degree of portability win it a perfect place in the tech stack of cloud-native apps. In fact, Golang was used to create high-end cloud computing tools like Istio, Kubernetes, and Docker.

2. Distributed Network Services

Concurrency is everything for network systems. Also, Go’s native concurrency features like channels and goroutines, are perfect for this type of work. Thus, a lot of Go programs focus on remote functions, networking, and cloud resources. Database servers, APIs, and web architectures are some examples.

3. Fintech Apps

The fintech industry is one of the most targeted industries by hackers as one-fourth of all malware attacks are directed at financial technology companies. So, fintech app developers need to be a bit careful while writing any piece of code.
