You will create a user interface for someone to create and manage a number of Doctor Who TV episodes. The information will be persisted in a Firebase database.

	import { Store } from "./store";

	interface IUser {
	username: string;
	}

	interface IProduct {
	name: string;
	description?: string;
	price: number;

	// Runtime functions
	const $history = [];
	let $historyCursor = -1;
	let $stack = [];
	let $nextHeapId = 1;
	let $heap = {};
	let $body = $nativeDomToVDom(document.body);
	let $heapOfLastDomSync = $heap;

	function $pushFrame(funName, variables) {

	; This program asks the user for their age, and then
	; calculates the year that they were born in and prints it out to the user.

	SECTION .data
	; these are string constants
	ask_number db 'How old are you? '
	answer db 'So you were born in '

	SECTION .bss
	; this buffer is used to store the user's input, which are expected to be all digits

	section .data
	question: db "Are you sure? (y/n)", 10
	affirmative: db "Okay, fine.", 10
	negative: db "Nevermind, then.", 10

	section .bss
	input: resb 255

	section .text
	global _start

	import { Subject, BehaviorSubject, Observable } from "rxjs";

	const subject: Observable<string> = new BehaviorSubject("Hello");

	subject.subscribe((value) => {
	console.log("1st sub: received value", value);
	});

	subject.next("How are you doing?");
	subject.next("Goodbye");
