Can you tell about Go in general — what kind of language it is, its features?

Go (Golang) is a compiled programming language developed by Google. Its main features:

• Simplicity and conciseness — minimalist syntax, easy to read.
• High performance — close to C/C++, thanks to compilation into machine code.
• Built-in support for concurrency — goroutines and channels make it easy to write parallel code.
• Static typing — type errors are detected at compile time.
• Garbage collection — automatic memory management.
• Standard library — rich and covers many tasks, including networking, cryptography, web servers.

Example of a simple program in Go:

package main
import "fmt"
func main() {
    fmt.Println("Hello, Go!")
}

Go is often used for creating server applications, microservices, CLI tools, and system software.
