Best practice of counter in map struct golang-CodePudding

I have a code that is not clean. I want to increment Counter in struct of NameLike but I think this is not effective.

package main

import "fmt"

type NameLike struct {
    Name    string
    Counter int
}

func main() {
    sosmed := make(map[string]NameLike)

    sosmed["rizal"] = NameLike{"Rizal Arfiyan", 10}

    for i := 1; i < 10; i   {
        sosmed["rizal"] = NameLike{
            Counter: sosmed["rizal"].Counter   1,
        }
    }

    fmt.Println(sosmed)
}

do you have any ideas regarding this code, to make it clean?

sosmed["rizal"] = NameLike{
    Counter: sosmed["rizal"].Counter   1,
}

CodePudding user response：

There are a few approaches you could take to simplify this code.

The current map passes NameLike by value. If you pass by reference, you can simplify things a bit:

package main

import "fmt"

type NameLike struct {
    Name    string
    Counter int
}

func main() {
    sosmed := make(map[string]*NameLike)
    sosmed["rizal"] = &NameLike{"Rizal Arfiyan", 10}

    for i := 1; i < 10; i   {
    sosmed["rizal"].Counter  
    }

    fmt.Println(sosmed["rizal"])
}
