Async / Await with Babel.js

Natively with Node.js

As of writing this (26-12-16) Node does not support Async / Await yet. To check if it does now head over to node.green. In case you're thinking, but the harmony flag!, yes, node at this moment has a harmony flag that enables an unstable implementation of Async / Await. It is however, for good reason marked unstable. Use features behind harmony flags for testing only. Not for things that will at any point in the future be deployed.

Compiling with Babel

In short, babel lets you use next generation JavaScript today. If you want to use some language feature that is marked red on node.green or for other environments like browsers, one of these compatibility tables chances are Babel can get you there. The cost will be having to compile your source code from JavaScript to JavaScript. The difference being that some language features will be rewritten

Getting Started With ESLint

So you have a JavaScript project and want to start linting it, great! There are a couple choices you need to make and a few things you should know. I will try to make the process a breeze.

Setting Up ESLint

Before we dive in, there are two things you'll have to keep in mind:

You can install ESLint globally and locally. I would advise you use the local installation method. We'll make it convenient later.
When running ESLint's initialization command: ./node_modules/.bin/eslint --init you'll get a few options to kick-start configuration. I would encourage you to opt to Use a popular style guide followed by picking the airbnb one. It is the most popular style guide and I feel a great starting point. You can always overwrite the rules later.
Complete the local installation guide.

Adding ES

Getting Started with NodeJS (WIP)

Learn as you go

Start with dreaming up something you want to build, then go and learn things as you go. Lookup or ask what the best way is to accomplish something.
