将函数主体/定义作为参数传递给golang中的函数调用

Question

I am come across the following question recently in using golang. Is it ok to pass a function body to a function call, like javascript. e.g. setTimeout(function(i){console.log("input:", i)}, 1000).

It's pretty common to pass an anonymous function to another function in javascript. I was wondering if is the same in go?

package main

import (
    "fmt"
)

type HandlerFunc func(int)

func main() {
    // define a function as object/variable?
    hnd := func(in int){
        fmt.Println("func handler returns input", in);
    }
    a:=HandlerFunc(hnd) //pass function object/variable to type HandlerFunc
    a(10)

    // pass function body directly to type HandlerFunc
    b:=HandlerFunc(func(_in int){
        fmt.Println("another func handler returns input", _in);
    })
    b(100)

    fmt.Println("Hello, playground")
}

They both works, but I was wondering if there is any difference between these two use, And which one is more preferable?

There is no difference, use the one that better fits your style.
