ECMAScript 6, the new JavaScript standard that’s being released this year, is a huge improvement and upgrade and change from previous versions.   That’s because ES6 is in a new world, with different requirements.  What are these changes, and what led the ES6 designers to make them? How will this affect the ways in which we’re using JavaScript, and computers in general?  How do these changes reflect the new ways in which we’re using computers, which weren’t around when JavaScript was first written? In this talk, Allen Wirfs-Brock reviews not just the changes in JavaScript, but the reasons behind them, and how modern computing differs from what we used just a decade or two ago.
