JavaScript Best Practices

Code conventions

Closing/opening brackets

Although this isn't a problem in other languages, because of semicolon insertion, there could be problems if you don't place the bracket on the opening line:

// no:
function()
{

$ sudo -i
$ yum list redis
$ redis.x86_64 2.6.13-1.el6.remi  remi

But today we want compile redis from source (see http://redis.io/download)

$ yum install make gcc tcl
$ cd /usr/local/src

Thanks everyone for participating in the quiz!
Many of you have posted correct answers.

What we know:

A top-level App component returns <Button /> from its render() method.

Question:

>What is the relationship between `` and this in that `Button`’s `render()`?

From Meteor's documentation:

In Meteor, your server code runs in a single thread per request, not in the asynchronous callback style typical of Node. We find the linear execution model a better fit for the typical server code in a Meteor application.

This guide serves as a mini-tour of tools, trix and patterns that can be used to run async code in Meteor.

Basic async

Sometimes we need to run async code in Meteor.methods. For this we create a Future to block until the async code has finished. This pattern can be seen all over Meteor's own codebase:

import { Observable } from 'rxjs/Observable';
// then patch import only needed operators:
import 'rxjs/add/operator/map';
import 'rxjs/add/observable/from';

const foo = Observable.from([1, 2, 3]);
foo.map(x => x * 2).subscribe(n => console.log(n));

So. Your friend's about to teach you how to make a website. Great!

You make a file, and you save it as 'index.html'. Why it's called 'index' isn't really explained to you, but whatever.

You type the following.
