Download as PPTX, PDF1 like770 views
ES6 introduced 10 new features to the JavaScript language including let and const keywords for block scoping, default parameters, template strings, arrow functions, rest parameters, generators, maps, classes, modules, and more. While feature complete in 2014 and standardized in 2015, browser support is still evolving as vendors implement the new standards. Transpilers like Babel can convert ES6 code to ES5 to provide support across browsers.
