What are the main features of the Go language?

Main features of the Go (Golang) language:

• Simplicity and conciseness: Go's syntax is minimalist, making code easier to read and maintain.
• Static typing: strict type system with type inference capabilities.
• High performance: compiled into machine code, close in speed to C/C++.
• Built-in concurrency support: goroutines and channels make it easy to write parallel and asynchronous programs.
• Garbage collection: automatic memory management.
• Standard library: a rich set of packages for networking, input/output, cryptography, and more.
• No class inheritance: instead, composition and interfaces are used.
• Tools: built-in tools for code formatting (gofmt), testing, profiling.

Example of a simple goroutine:

package main

import (
    "fmt"
    "time"
)

func sayHello() {
    fmt.Println("Hello from goroutine")
}

func main() {
    go sayHello() // start goroutine
    time.Sleep(time.Second) // wait for completion
}
