History of Golang
Go, or Golang, is an open-source programming language developed by Google. It is a C-based language with static typing capability.
Go creators aimed to develop a powerful language like C++ that can work with large-scale projects, offering security and efficiency. They also wanted to provide simple, easy-to-type code like Python and create a fast-working alternative to existing languages.
In practice, story of Go started in 2007 when three Google engineers, Robert Griesemer, Rob Pike, and Ken Thompson, who were familiar with Unix, began to design a project.
In November 2009, Go was presented as an open-source project where community members could code and collaborate. Then, in April 2012, version 1.0 was released. Throughout its existence, Golang has evolved. New updates and features, such as generics in 2022, emerge regularly.
Go participates in many open-source projects, such as the popular image manipulation library Image Magick, the distributed version control system Git, and the popular text editor Vim. The Go programming language is also a big deal for developers working with Kubernetes, an open-source ecosystem for containerized applications. Golang is one of the most performant languages for implementing distributed systems, such as distributed key-value systems and databases. This language is well known for its scalability and performance, which helps create microservices.
Go has gained popularity among developers and top organizations, such as Google, Dropbox, Netflix, Twitch, MongoDB, SoundCloud, and Uber.

Comparing Golang with Other Languages
How does the Go differentiate from other programming languages? Let's weigh up the similarities and differences between Golang and some of the most popular software development languages.
Golang vs. Rust
Both Golang and Rust support static typing, concurrency, and pointer safety.
In practice, Go language has garbage collection, while Rust doesn't.
Golang is easy to learn, has a simple syntax, and has appealing documentation. Rust, By contrast, is complex and challenging to understand and provides non-ordinary language construction and concepts.
Go's code is clean and readable. Rust's code is high-quality due to its type system and rigorous compiler checks.
Golang has an active and meaningful community with many libraries and frameworks. Rust has an active and growing community with an increasing number of frameworks and libraries.
Golang vs. C++
C++ doesn't have automatic memory management. The Go programming language has garbage collection that ensures memory safety and efficient memory management features, which help reduce runtime errors and dependencies.
Go is a simpler language than C++, although Golang's syntax is similar to C++.
Go supports concurrency through goroutines and channels. C++ also offers concurrency using coroutines.
Golang is a newer language than C++. So, its library is much smaller than the C++ language.
Golang vs. C#
Go and C# are statically typed languages with features such as garbage collection, type safety, and built-in concurrency support.
Golang compiles straightforwardly to machine code without using mediators like .NET Intermediate Language or Java bytecode. C# is a Windows-based language compiled using Microsoft Intermediate Language (MSIL), which later compiles to native machine code during runtime.
In practice, Go programming language boasts exceptional performance because of rapid compilation time without intermediate or low memory overhead. C# utilizes the Just-in-Time compilation principle.
Both languages are easy to learn because of clear documentation and simple syntax. Golang and C# have robust standard libraries that contain networking data structures, web programming, concurrency, and other features.
Golang vs. Java
Go language is quicker because it is compiled directly, while Java uses a virtual machine (VM) that reads code and executes corresponding commands.
Java has a vast library compared with small-sized Go's standard library.
Why Golang is Ideal for Microservices
Go is proving its efficiency in developing distributed systems. Golang is suitable for the modular nature of microservices, which are sets of specific functions. Let's break down the core reasons why Go is a perfect programming language for microservices.
