Why Golang in Exoreaction?


At exoreaction we use golang and we have an expert on the subject. My partner Sindre. You will find many of the projects he has worked on in Cantara. Later I will tell you about some really interesting ones.


Go, also known as Golang, has gained popularity in the tech industry for several reasons, making it a preferred choice for many companies. Some key factors contributing to the popularity of Go include:

1. Concurrency Support:

Go has built-in support for concurrency, making it easy to write concurrent programs. The language includes goroutines, lightweight threads managed by the Go runtime, and channels, which facilitate communication between goroutines. This makes it efficient for developing scalable and concurrent applications.

2. Efficiency and Performance:

Go is designed with a focus on simplicity and efficiency. It compiles to machine code, providing fast execution and performance. Its garbage collector is optimized for low-latency, making it suitable for building high-performance applications.

3. Static Typing:

Go is statically typed, which means that type checking is done at compile-time. This helps catch errors early in the development process, making the code more reliable and less error-prone.

4. Simple and Readable Syntax:

Go has a clean and straightforward syntax, making the code easy to read and maintain. Its simplicity is conducive to quick learning and adoption, especially for developers transitioning from other languages.

5. Standard Library:

Go comes with a comprehensive standard library that includes packages for handling tasks such as networking, encryption, and file I/O. This reduces the need for external dependencies and provides a consistent set of tools for developers.

6. Cross-Platform Compatibility:

Go is designed to be cross-platform, and its compiler generates binaries for different operating systems without requiring modification to the code. This portability is beneficial for building applications that can run seamlessly across various environments.

7. Open Source Community:

Go is an open-source language with a thriving community of developers contributing to its ecosystem. This community support has led to the creation of numerous libraries, frameworks, and tools that enhance the development experience in Go.

8. Scalability:

Go is well-suited for building scalable systems, and many large-scale applications and services, including those at companies like Google, Dropbox, and Docker, have been successfully built using Go. Its concurrency model and performance characteristics make it suitable for handling large numbers of simultaneous connections.

9. Strong Backing:

Go was developed by Google, which provides it with a strong backing and support. This backing has instilled confidence in companies considering Go for their projects, knowing that it is developed and maintained by a reputable tech company.

10. Effective for DevOps:

Go's efficiency, static typing, and cross-platform compatibility make it well-suited for building tools related to DevOps, such as container orchestration tools (e.g., Kubernetes and Docker) and infrastructure-related software.

Overall, the combination of performance, simplicity, concurrency support, and a strong community has contributed to the widespread adoption of Go in the tech industry.

Tech Companies using Golang

Several prominent tech companies have adopted Go (Golang) for various purposes, including backend development, microservices, infrastructure tools, and more. Keep in mind that the technology landscape is dynamic, and the usage of programming languages may evolve over time. Here are some companies known to use Go:

1. Google:
Go was developed by Google, and many internal projects at Google are written in Go. Google's Kubernetes, a popular container orchestration platform, is also written in Go.

2. Uber:
Uber has been using Go for building various components of its infrastructure, including some backend services.

3. Dropbox:
Dropbox has adopted Go for certain backend services and infrastructure components.

4. Docker:

What should I do to learn Golang?

Learning Go (Golang) can be a rewarding experience, especially if you're looking to build scalable and efficient applications. Here's a step-by-step guide to help you get started with learning Go:

1. Understand the Basics:
Start by understanding the fundamentals of the Go language. Familiarize yourself with the syntax, data types, variables, and basic control structures (such as loops and conditionals). The official Go Tour is an excellent resource for this: A Tour of Go.

2. Set Up Your Development Environment:
Install the Go programming language on your machine. You can download the official distribution from the official Go website. Follow the installation instructions for your operating system.

3. Read the Official Documentation:
The official Go documentation is comprehensive and well-written. Read through the official documentation to gain a deeper understanding of the language features, standard library, and best practices.

4. Code Along and Practice:
The best way to learn any programming language is by writing code. Start with simple programs and gradually move on to more complex projects. Practice is crucial for solidifying your understanding of the language.

5. Explore Go Packages and Libraries:
Go has a rich standard library, and there are many third-party packages and libraries available. Explore the standard library and learn how to leverage existing packages to enhance your programs. The Go documentation is an excellent resource for this.

6. Concurrency and Goroutines:
One of the key strengths of Go is its support for concurrency through goroutines. Learn how to use goroutines and channels for concurrent programming. Understanding concurrency is essential for building scalable and efficient applications.

7. Build a Small Project:
Apply your knowledge by working on a small project. This could be a web application, a command-line tool, or any other project that interests you. Building real-world projects is a great way to reinforce your learning.

8. Explore Web Development with Go:
Go is often used for building web applications and APIs. Explore web development in Go using frameworks like Gin or Echo. Learn how to handle HTTP requests, route traffic, and work with databases.

9. Read Books and Tutorials:
There are several books and online tutorials that can help deepen your understanding of Go. Some recommended books include "The Go Programming Language" by Alan A. A. Donovan and Brian W. Kernighan and "Programming in Go" by Mark Summerfield.
