How to Learn Golang
What do readability, concurrency, and gophers have to do with web development? They all are part of Google’s brainchild, a programming language called Golang, commonly referred to as Go.
Released in 2009 after being created for in-house purposes, Golang is a popular programming language that’s loved for its simplicity, scalability, and adorable mascot (a gopher).
If you’re interested in web development as a career or hobby, Golang is a great language to learn. In this article, we’ll discuss how you can learn this programming language.
What Is Golang?
Golang, an open-source language based on the C programming language, focuses on efficiency, which leads to faster software and apps. Some of the companies where developers use Golang include Google, Apple, Facebook, Docker, The New York Times, and BBC.
There are several reasons why developers choose to use Golang. First, it is fast. It is a compiled language, which means that once a program has been compiled, it will run more quickly than a program written in an interpreted language.
Second, Golang is primed for scalability with something called Goroutines. Goroutines are functions that can run simultaneously and independently. You can run many, even millions, of Goroutines without crashing your program. Running these Goroutines simultaneously is called “concurrency” and is part of what makes Golang so powerful.
Third, Golang comes with comprehensive programming tools, like editors, IDEs, plugins, and a GitHub repository. It’s an open-source project that a lot of people are working on, with the backing of Google, so there are plenty of resources available to help you build projects.
What Is Golang Used For?
Golang is used in a variety of industries and use cases. Here are just a few:
- Cloud services. Google uses Golang to build cloud infrastructure with its Google Cloud Platform. Other businesses are also using Golang for their cloud services, such as Dropbox, Terraform, Kubernetes, and Docker.
- Media platforms. Because of its speed and scalability, Golang is used on platforms that have high load counts, such as YouTube, SoundCloud, and Netflix.
- News outlets. The news outlet BBC uses Golang for their back end development and internal analytics services.
- On-demand services. Again, because of its speed, Golang is ideal for services that need to respond quickly to user information. An example is Uber’s need to improve map processing speeds. Uber and other companies use “geofencing”, a process by which an app can identify a user’s location and thereby recommend nearby services. Golang provides the speed necessary to provide accurate recommendations based on a user’s location.
Golang is easy to learn if you already have a background in C or Java. For many developers with development experience, transitioning to Golang has been a popular move. But even if you don’t know C or Java, Golang can be a good first language to learn, as it is in demand right now.
One thing to consider is that, even though it has fast execution, writing Golang can be time-consuming. You may need to write many lines of code to accomplish something that can be done with just a few lines in a language like Python. As with any decision about which technology to use for a given project, as a developer you’ll need to think about the pros and cons of using Golang over another language.
Before learning Go, you should be familiar with the concept of functions in programming. You will also need some kind of text editor or IDE (Integrated Development Environment) and some knowledge of how to use your command terminal.
According to Stack Overflow’s 2020 Developer Survey , globally, Golang is the third-highest paying programming language. People who have this skill earn on average $74,000 a year. In the United States, Golang comes in second, with average salaries at $140,000. As of this writing, there are over 6,000 jobs on LinkedIn that mention Golang , with job titles like Golang developer, software engineer, and technical lead.
How Long Does It Take to Learn Golang?
If you already know C or Java, Golang is easy to learn, and you can start writing programs in just a few days. If you do not know C or Java, it will take you two to three months to learn to use Golang professionally. You will want to continue practicing your skills for several more months if you want to become a Golang developer.
How to Learn Golang: Step-by-Step
Depending on your familiarity with programming and your learning preferences, there are several ways to get started with Golang. Some developers prefer to take courses or read books before jumping into a new technology. While these steps may differ for you, here are our big-picture tips for getting started with Go.
