What is the difference between a method and a function, and what are the features of their use?

In Go, a function is an independent block of code that can be called by name and can accept parameters and return values.

A method is a function associated with a specific type (for example, a struct). A method is declared with a receiver, which determines to which type it belongs.

Features of usage:

• A method allows working with data of a specific type, using the receiver inside the method body.
• Methods help organize code and implement behavior for types, bringing Go closer to object-oriented style.

Example:

package main
import "fmt"

type Person struct {
    Name string
}

// Method with receiver of type Person
func (p Person) Greet() {
    fmt.Println("Hello, my name is", p.Name)
}

// Regular function
func Add(a, b int) int {
    return a + b
}

func main() {
    p := Person{Name: "Ivan"}
    p.Greet() // calling the method
    fmt.Println(Add(2, 3)) // calling the function
}
