Can you pass functions as parameters in Go?

Hi everyone! I just started learning Go, and I have a question. I'm used to languages where functions can be passed as arguments to other functions (for example, in JavaScript or Python). But in Go, I'm not sure if this is possible. I tried to write a simple calculator that would take an operation (addition, subtraction) as a parameter, but I couldn't get it to work. Here's what I tried: ```go package main import "fmt" func add(a, b int) int { return a + b } func subtract(a, b int) int { return a - b } func calculate(a, b int, op func(int, int) int) int { return op(a, b) } func main() { result := calculate(10, 5, add) fmt.Println(result) } ``` The code compiles and works, but I'm not sure if this is the correct syntax. Why do you need to write `func(int
