 - The [`let`](/en-US/docs/Web/JavaScript/Reference/Statements/let) and [`const`](/en-US/docs/Web/JavaScript/Reference/Statements/const) bindings in the global level have been made compliant with ES2015 semantics. See {{bug(589199)}} and the blog post ["Breaking changes in let and const in Firefox Nightly 44"](https://blog.mozilla.org/addons/2015/10/14/breaking-changes-let-const-firefox-nightly-44/). In addition, `let` is now available to default Web JavaScript (strict and non-strict) and does not require a version opt-in anymore ({{bug(932517)}}).
 - If [typed arrays'](/en-US/docs/Web/JavaScript/Typed_arrays) (like {{jsxref("Int8Array", "Int8Array")}}) and {{jsxref("ArrayBuffer", "ArrayBuffer")}}) constructors are called as a function without the {{jsxref("Operators/new", "new")}} operator, a {{jsxref("TypeError")}} is now thrown as per the ES2015 specification ({{bug(980945)}}, {{bug(1214936)}}).
 - The {{jsxref("RegExp")}} sticky flag now follows the ES2015 standard for [anchored sticky regular expressions](/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/sticky#anchored_sticky_flag) ({{bug(773687)}}).
