tour: function values
Context: https://go.dev/tour/moretypes/24
the example shown in the code editor is not an ideal example for beginners, and I do find it confusing.
func compute(fn func(float64, float64) float64) float64 {
return fn(3, 4)
}
func main() {
hypot := func(x, y float64) float64 {
return math.Sqrt(x*x + y*y)
}
fmt.Println(hypot(5, 12))
fmt.Println(compute(hypot))
fmt.Println(compute(math.Pow))
}
Could the example be simpler?
I have a simpler one that gets the lesson of the function using values and can be used as a variable
func modFunc(a,b int) int {
return a % b
}
func main() {
mod := modFunc
result := mod(8,3)
fmt.Println( result )
}
