When I first heard about the next version of JavaScript - known as ECMAScript 6 (ES6 for short) or JavaScript Harmony - I got really excited about all of the new features that we’d be getting to simplify and improve our lives as JavaScript developers… until I thought about it for 5 more seconds and realized that my kids would probably all be grown and moved out before I didn’t need to support any browsers that don’t support ES6, so I may never actually get to use it. I’m discovering that ES6 might be more usable right now than I thought it would be.
