What is Golang?

Golang is a statically typed, compiled language reminiscent of C. It was created by Google as a response to the growing demand for cloud solutions. It is characterized by a number of solutions that facilitate learning and working with a language, while not limiting its functionality. The unique features of the language include constructs that allow you to easily write programs that use multithreading: goroutines and channels.

What is goroutine? This is a so-called light thread that shares memory with other gorutines but has its own execution context. It differs from the standard system thread in that it is much "cheaper" to create and use, which allows you to start thousands or even hundreds of thousands of goroutines in one program.

What is a channel? A channel is a simple FIFO queue in the program's memory, it is used to improve communication between goroutines in Golang according to the "do not communicate by sharing memory; instead of share memory by communicating" principle. According to this, communication between threads should take place by sending messages between them, thus eliminating the need to block resources using mutexes and thus eliminating the cause of a significant number of errors in concurrent programming.
