“Most of the ES2015 functionality in Microsoft Edge is ready for use and on by default without a flag. This includes arrow functions, enhanced object literals with concise methods and other syntactic shorthands, template strings, rest parameters, the spread operator, let and const bindings, proxies, symbols, iterators, new built-ins such as Typed Arrays, Map, Set, WeakMap, WeakSet, and a slew of new methods on existing prototypes for String, Array, Number, and new utility methods for Object and Math. This is not even a complete listing; see our roadmap on Microsoft Edge Platform Status for an always up-to-date view of what is enabled.
