What is Go?
Go, often referred to as Golang, is developed as a community-lead open source project in Google. It is meant to be simple to learn, straightforward to work with, and easy to read. It is a language for building cross-platform enterprise applications, as well as a means of a developing code that can run anywhere.
What is Golang Used for?
Unlike C++, Go does not have a very rich feature set, but it has concurrency and functional programing features. Go programming is mainly used for developing stand-alone command-line apps, scripts Network, and Web servers and producing maintainable code.
Go is most suited for developing a few key application types:
Distributed networked services
Go’s native concurrency features are very well suited for developing networking applications. As a result, many Go-projects are for networking, distributed functions and cloud services, such as: APIs, web servers, minimal frameworks for web apps, etc.
Features like concurrency, networking, and its high degree of portability, make Go well-suited for building cloud-native apps. Actually, Go was used to build and set one of the cornerstones of cloud-native app development, the app containerization system Docker.
Replacement for existing infrastructure
As the existing Internet infrastructure is aging, it needs to be rewritten in another language. Golang web framework is an excellent choice for this because it provides many advantages – better memory safety, easier cross-platform development, and clean code base which allows easier future maintenance.
Advantages of using Google Golang
Described as “a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language”, Go also avoids much of the overhead of C-style, including files and libraries, and so it has become the favorite of many developers.
Fast compiling is one of the most important features of Go. Even though Go binaries run more slowly than their C-counterparts, the difference is negligible in most apps. Golang’s performance is generally as good as C, and much faster than other languages known for their development speed.
When you create executables in Go, they can stand alone without default external dependencies. The Go toolchain is available for use in various operating systems and hardware platforms, and it can be used for development and compiling of binaries across platforms.
Go has the ability to satisfy many common programing needs. It has many built-in functionalities, such as “goroutines” for concurrency and threadlike behavior, automatic memory management capabilities including garbage collection, and additional capabilities available in the library packages.
Go operates without sacrificing access to the underlying system. It can talk to external C libraries or make native system calls. It can also interface with low-level Linux functions and namespaces.
Go toolchain is available for free download as a Linux, MacOS or Windows binary, or as a Docker container. It is included in many popular Linux distributions, which make it easier to deploy Go source to those platforms. There is also strong support for Go across many third-party development environments like Microsoft Visual Studio Code and ActiveState’s Komodo IDE.
