A guided tour of some of the cool new features coming to the next version of Javascript! We'll take a look at generators, classes & modules and how they'll help your JavaScript development. We'll also take a look at current browser support and how to use transpilers to start using these features today.

1. ES6
A LOOK INTO YOUR FUTURE
Created by /Jason Sich @jasich

2. WHAT IS ES6?
ECMAScript is the standard for the JavaScript language
ES6 is the coming 6th edition of standard
Implemented by vendors (Chrome, Firefox, Node.js, IE)
Only a draft spec now, expected to be finalized in 2015

3. HISTORY: IN THE BEGINNING
Created by Brendan Eich at Netscape mid 90's
Became a thing
Got standardized with ECMA
TC39 is the technical committee in charge

4. HISTORY: CH CHA CHANGES
v2 for ISO
v3 brought try/catch, Regex, & other
v4 stalled out

5. HISTORY: NOT TO BE
Netscape tanked, Microsoft soared, & dev stopped
Started again in 2005
Committee split into two
ES4 committee looked to make major changes
Subcommittee focused on smaller incremental change
(ES3.1)

6. HISTORY: HARMONY
In 2008 the groups were brought back together
ES4 was abandoned, wanted to avoid confusion
ES5 was created as a compromise, mostly based on ES3.1
ES6 is a work to harmonize TC39 & the ECMAScript
language

7. WHAT'S IN ES6?
arrows, classes, enhanced object literals, template strings, destructuring, default + rest + spread, let
+ const, iterators + for..of, generators, unicode, modules, module loaders, map + set + weakmap +
weakset, proxies, symbols, subclassable built-ins, promises, math + number + string + object APIs,
binary and octal literals, reflect api, tail calls

8. 3 THINGS TO TALK ABOUT TODAY
Modules
Classes
Generators/Iterators
other stuff too

9. CODE EXAMPLE

10. CURRENT SUPPORT
Browsers
Node
Compliers/Polyfils
Checkout the ES6 Compatibility Table

11. HOW TO SUPPORT IT
Use a compiler to compile ES6 code to ES6
Like
Traceur can precompile files to ES5 using node.js
Or it can compile at runtime (like my example code)
Use polyfils to use a subset of features you want
Ask people to turn on experimental flags?
github.com/google/traceur-compiler

12. WHO'S USING IT?
Ember
Using ES6 modules
Angular
Using ES6 modules & classes
Adding annottation support for AtScript via Traceur
