Rust VS Go - A very small taste of what it looks like

small_taste_example.go

package main

import (
	"fmt"
	"sync"
)

func main() {
	nums := []int{0, 1, 2, 3}
	noms := []string{"Tim", "Eston", "Aaron", "Ben"}

	var wg sync.WaitGroup

	evens := make([]int, 0)
	for _, v := range nums {
		if v%2 == 0 {
			evens = append(evens, v)
		}
	}
	wg.Add(len(evens))
	for _, v := range evens {
		go func(index int){
			msg := fmt.Sprintf("%s says hello from a lightwieght thread!", noms[index])
			fmt.Println(msg)
			wg.Done()
		}(v)
	}
	wg.Wait()
}
