Why Go is better than others nowadays?

The following is not an attempt to convince anyone that one technology is better than the other, instead, I like to explore the strong points of language so we can better choose the appropriate tool for a given task.

I have been working with Node.js for more than five years now and recently started using Go to build various small and medium-sized projects. At this point, I like to document my thought process for choosing a language for solving a given task.

Go or GoLang, as it is called, is a robust system-level language used for programming across large-scale network servers and big distributed systems. Golang emerged as an alternative to C++ and Java for the app developers in the context of what Google needed for its network servers and distributed systems

Let's discuss one by one factor which makes go different from the majority of existing programming language.

Multithreading And Concurrency

A vast majority of programming languages lack concurrent execution when working with multiple threads. They often slow down the pace of programming, compiling and execution. This is where Go comes as the most viable option to support a multi-threading environment and concurrency both.

With time the hardware manufacturers have kept on adding more core to the system to ensure better performance.

Go was conceived at the time multi-core processors became widely available across sophisticated hardware. The creators of Go gave particular focus on concurrency. Go works with goroutine which allows it to handle concurrently large number of tasks.

Simplicity of Go

No Generics:
Generics or templates which remained a mainstay for various programming languages often add to the obscurity and difficulties of understanding. Go designers by deciding to go without it made things simple.

Single Executable:
GoLang comes without any separate runtime library. It can produce a single executable code that can be deployed by just copying. This helps in removing all the concerns of committing mistakes on dependencies or versions mismatch.

No Dynamic Libraries:
Go just decided to do away with any dynamic library to keep the language simple and straightforward. Although, in the latest Go 1.10 version the developers are given the option to upload dynamic libraries through plug-in packages. This has just been included only as an extended capability.
