Introduction - What is Golang?

New programming languages emerge regularly in the world of software and technology.  Having said that, one such language that has gained considerable attention is Go. Go is often referred to as Golang. 

Golang was developed by Google engineers Robert Griesemer, Rob Pike, and Ken Thompson. Golang or Go was designed to address the limitations of existing languages. Also, to offer a streamlined approach to building robust and efficient software.

Aspect Description
Purpose Build simple, secure, scalable systems with Go
Supported by Google (an open-source programming language)
Learning Curve Easy to learn and great for teams
Key Features Built-in concurrency and a robust standard library
Ecosystem Large ecosystem of partners, communities, and tools

The Story Behind Go: A Language Built to Solve Problems

Story behind go language

How did Golang or Go come into existence?

Go came to life to tackle Google’s own software challenges. It all started when Google faced difficulties with their existing tools, like C++. Moreover, they saw a growing demand for a language that could handle the power of modern processors with multiple cores.

Around 2007, Google’s smart minds set out to create Go. Their goal? To make a language that was simpler than what was already out there. Also, without taking away the good parts from languages like C++, Python, and JavaScript. They wanted a language that was user-friendly and efficient.

Subsequently, in 2009, they shared Go with the world as an open-source project. This meant that anyone interested could join in, share ideas, and write code.

Again, in 2012, Go version 1.0 made its official debut.

As time rolled on, Go didn’t stand still. It kept improving and gaining new features. Finally, Go was introduced with a new feature called generics in 2022. This feature added enhanced Go’s versatility and capability. With every enhancement, the popularity of Go soared.  


Tech giants such as Cloudflare, Google, MongoDB, Dropbox, Twitch,
Netflix, SoundCloud, Uber
adopted Go for their development projects. .

So, Go  was born out as a solution to some real problems. Google’s smart minds developed Go with an intent to offer a simple and  efficient programming language to the developer community. Thus, Go is a language embraced by a community of developers and companies looking to build amazing things.

What is Go used for?

Use CaseKey Attributes
Web Application DevelopmentScalability, Efficiency
System-level ProgrammingHigh Performance, Low-Level
Networking ApplicationsConcurrency, Network Services
Distributed SystemsMicroservices, Concurrency
Container EcosystemDocker, Kubernetes Integration
Cloud ServicesEfficiency, Serverless Support
Command-Line ToolsSimplicity, Performance
DevOps & InfrastructureAutomation, Management Tools

Go is a programming language that software developers use to build different types of software:

  • To Develop Network ServicesGo is particularly suitable for building network services including web servers, APIs, and mini frameworks for web applications.
  • Cloud-Native DevelopmentMany cloud platforms such as Kubernetes and Google Cloud were developed on Go.  Go’s concurrency and networking features makes it highly portable across various platforms.
  • Replacing Old Infrastructure:  Go was used to rewrite many old infrastructure. This was an attempt to modernize the obsolete infrastructure obsolete over time. For instance, a new version of the Network Time Protocol (NTP) – an internet protocol for clock synchronization among networks – depends heavily on Go.
  • Building Small Tooling Items Go can function on its own without any dependency on other languages or tool. So, it is well-suited for building small tooling items. These can launch quickly and be packaged for redistribution at a moment’s notice.
  • News Portals:   Media giant BBC uses Go for its backend development. It’s probably safe to assume Go’s capacity for multithreading to maximize CPU usage helps more often than not when it comes to managing a massive multimedia website.

What Are the Latest Advancements in Go Technology?

With the release of Go 2.0, Go technology has better support for error handling, generics, improved package management, and enhanced tooling. Let’s take a closer look at it down below: 

Generics: It promotes flexibility and code reusability. Golang developers can use functions and data structures to work with different types. It also simplifies the process of creating libraries and data structures. With the release of generics, Go continues to become a more powerful and versatile language. 

Enhanced error handling: Even though error handling in Golang is straightforward and effective, it can lead to lengthy expressions and repetitive code. Error handling was the hot topic of debate among Golang developers. But Go 2.0 has introduced improved error handling with error values and additional context that makes it extremely easy to spot issues.  

Better Tools: The Golang ecosystem is known for its robust and straightforward tools. Better IDE, improved code analysis, and dependency management. This will not only streamline the development workflow but also boost productivity. 

Focus on WebAssembly: WebAssembly allows developers to run Golang code directly in web browsers. Go’s small binary size and high performance make it best suited for WebAssembly development. In the upcoming years, we can see massive support and optimizations for Go programs in the browser. In the coming years, Golang developers can build games using Goang. 

Expansion in Various Domains: The Golang ecosystem is continually growing. This opens up the possibilities of Golang in machine learning, web development, and cloud-native applications. This latest advancement in Go technology makes it an excellent choice for building a wide range of applications.
