FizzBuzz

You can write fizzbuzz quickly.

Installation

go get github.com/junpayment/fizzbuzz

DoSync/DoAsync

You can write fizzbuzz sync or async modes.

sync

package main

import (
	"fmt"
	
	"github.com/junpayment/fizzbuzz"
)

func main() {
	sets := fizzbuzz.DoSync(100)
	for _, set := range sets {
		fmt.Printf("%d : %s\n", set.Input, set.Res)
	}
}

async

package main

import (
	"fmt"
	
	"github.com/junpayment/fizzbuzz"
)

func main() {
	sets := fizzbuzz.DoAsync(100, 10)
	for _, set := range sets {
		fmt.Printf("%d : %s\n", set.Input, set.Res)
	}
}

enjoy!

Benchmark

Since fizzbuzz is processing with minimal overhead, the parallel processing context seems to take longer than usual.

I recommend DoSync.
