I've been deceiving you all. I had you believe that Svelte was a UI framework — unlike React and Vue etc, because it shifts work out of the client and into the compiler, but a framework nonetheless.

But that's not exactly accurate. In my defense, I didn't realise it myself until very recently. But with Svelte 3 around the corner, it's time to come clean about what Svelte really is.

Svelte is a language.

Specifically, Svelte is an attempt to answer a question that many people have asked, and a few have answered: what would it look like if we had a language for describing reactive user interfaces?

A few projects that have answered this question:

V8

V8 is Google’s open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node.js, among others. It implements ECMAScript and WebAssembly, and runs on Windows 7 or later, macOS 10.12+, and Linux systems that use x64, IA-32, ARM, or MIPS processors. V8 can run standalone, or can be embedded into any C++ application.

SpiderMonkey

SpiderMonkey is Mozilla’s JavaScript and WebAssembly Engine, used in Firefox, Servo and various other projects. It is written in C++, Rust and JavaScript. You can embed it into C++ and Rust projects, and it can be run as a stand-alone shell. It can also be [compiled](https://bytecodealliance.org/articles/making-javascript-run-fast-on

	#!/usr/bin/env python3
	# -- coding: UTF-8 --

	import socket

	server_address = '/tmp/example.sock'

	sock = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
	sock.connect(server_address)

	const EventEmitter = require('events')

	class MyClass extends EventEmitter {
	constructor() {
	super() // required

	this.emit('event', 100)
	}

	const { resolve } = require('path');
	const fs = require('fs');
	const readdir = promisify(fs.readdir);
	const stat = promisify(fs.stat);
