JavaScript to Rust Cheat Sheet

The goal of this is to have an easily-scannable reference for the most common syntax idioms in JavaScript and Rust so that programmers most comfortable with JavaScript can quickly get through the syntax differences and feel like they could read and write basic Rust programs.

What do you think? Does this meet its goal? If not, why not?

	// simple express server
	var express = require('express');
	var app = express();
	var router = express.Router();

	app.use(express.static('public'));
	app.get('/', function(req, res) {
	res.sendfile('./public/index.html');

	That’s one of the real strengths of Docker: the ability to go back to a previous commit. The secret is simply to docker tag the image you want.

	Here’s an example. In this example, I first installed ping, then committed, then installed curl, and committed that. Then I rolled back the image to contain only ping:

	$ docker history imagename
	IMAGE CREATED CREATED BY SIZE
	f770fc671f11 12 seconds ago apt-get install -y curl 21.3 MB
	28445c70c2b3 39 seconds ago apt-get install ping 11.57 MB
