Javascript for Node.JS

 - Recap of Intro and basics
   - The basics of Javascript syntax and semantics. We can keep this very short
     assuming everyone is geting it.
 - Advanced javascript
   - Advanced/newer Javascript features such as Generators, just enough as

   - Map, Reduce and using first class functions. We'll talk a bit about what a
     closure is and what that means for your Javascript code.
 - Async techniques
   - Basic async development programming techniques in Javasscript
 - Promises
   - The hows and whys of promises
 - Async await
   - How to take what you know about promises and apply to the new async...await
     synctax
 - Javascript tooling
   - Prettier, linters, flow. Tooling available to make Javascript development
     better

Node
