Concurrency

Golang:

package main

import (
	"fmt"
	"time"
)

func execute(codingninjas string) {
	for i := 1; true; i++ {
		fmt.Println(codingninjas, i)
		time.Sleep(time.Millisecond * 100)
	}
}

func main() {
	// Simple and concurrent go program
	go execute("First Statement ")
	execute("Second Statement ")
	fmt.Println("program ends successfully")
}

PHP (Vapm):

<?php

declare(ticks=1);

use vennv\vapm\CoroutineGen;

function execute(string $name)
{
    for ($i = 0; true; $i++) {
        echo "$name $i\n";
        yield CoroutineGen::delay(100);
    }
}

CoroutineGen::runNonBlocking(
    execute("First Statement ")
);

iterator_to_array(execute("Second Statement "));
