How to build a socket server with async and for-await.

	import { createServer, Socket } from "net";

	// Promisified socket.write().
	const write = (socket: Socket, data: Buffer \| string) =>
	new Promise((resolve, reject) =>
	socket.write(data as Buffer, (error: Error \| undefined) => {
	if (error) {
	reject();
	} else {

Implementing simple recursion as an iterator in Zig 0.11.0.

	const std = @import("std");

	const Buffer = std.ArrayList(u8);

	const source = [_]u8{ 1, 2, 3, 4, 5 };
	const expectedOrder = [_]u8{ 1, 2, 3, 4, 5, 5, 4, 3, 2, 1 };

	fn recursive(read: []const u8, write: *Buffer) !void {
	if (read.len > 0) {
	try write.append(read[0]);
