ES6, A Look Into Your Future
- 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 Checkout for the list.github.com/lukehoban/es6features
- 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
