Something about ES6 I want you guys to know

You may hear us talking about this "ES6" all the time. ES6 basically means: the latest version of JavaScript. It has a lot of really nice new features that makes life as developer easier. For you guys, you should remember the following:

During the NodeJS course, we will teach you some ES6 features, like Fat Arrow. It's extremely important to know whether a function comes from ES6 or from an older version of JavaScript. Why? Because browsers don't support every new feature just yet. With Node, on the other hand, you can always control which version of Javascript is running, because it's running on your computer, not in the browser. Node Version 6.x that you are running supports most ES6. So in summary: if you're working on the frontend, you probably don't want to use es6 just yet. In backend, type node --version to see which version you are running, and make sure everyone on the team has the same version by adding "engine" to package.json like so:

"dependencies": {
  ...
},
"devDependencies": {
  ...
},
"engines": {
  "node": ">=6.5.0" // this means you need 6.5 or higher
},

1. ES6: Fat Arrow functions

This is one example of how ES6 can help us write cleaner code. I'm adding this as first reading material because it's used a lot on the NodeJS documentation website, so it's a good idea to understand what this means. Bonus points if you write your callbacks this way.
