How do you define a function in Go?

Question

Khushi Singh · Answer

The 
Go programming language uses func as a function declaration keyword to create functions with names and parameter lists of typed input values and resulting return types inside curly braces {}.
Basic Syntax
func functionName(parameterName type, ...) returnType {
    // function body
}
Example
package main
import "fmt"
func greet(name string) string {
   return "Hello, " + name + "!"
}
func main() {
   message := greet("Go Developer")
   fmt.Println(message)
}
Explanation
The func keyword functions as the declaration element to establish functions.
and greet is the function name.
and This function requires one input parameter called name which is a string type.
and The function provides a result that takes the form of a string value.
and Every Go application has the main function serving as its starting point.
The 
Go language enables functions to accept multiple parameters while enabling users to return multiple values and introduce named return components as well as anonymous functions. Starting every function definition in Go requires the usage of
func followed by the function signature then the body.
