Return function in Go

Return function

package main

import (
	"fmt"
)

func main() {
	x := bar()
	fmt.Printf("%T\n", x)
	/
	i := x()
	fmt.Println(i)
}



func bar() func() int {
	return func() int {
		return 451
	}
}

// when we run "bar()",
// it gives us "funct()int",
// we assign it to"x"
// The type of "funct() int" is the type  "func() int"
// When we execute it, it returns "451", which we assign to "i"
