Upgraded babel-polyfill from 6.9.0 to 6.9.1

Changelog:

Version 6.9.1

6.9.1 (2016-05-29)

Also released 6.9.2 to fix a missing dependency issue for the switch to regenerator-runtime

Just 2 fixes this release!

• A class property fix (set this correctly when using async arrow function class properties without a super class).
• A fix for react-constant-elements plugin to help optimize react more (the plugin wasn't applying to JSX with text).

Also, thanks to @mucsi96 for catching the extraneous code coverage comments we were leaving when publishing!

We are removing/deprecating babel-regenerator-runtime in favor of depending on the original regenerator-runtime since the differences are resolved. Thanks to (@benjamn) for the suggestion to maintain it (and for originally creating it!).

Bug Fix

• babel-core
  • #3508 (https://github.com/babel/babel/pull/3510) Assign _this to this when there is no Superclass in a Class when using class properties. Fixes T7364. (@ehjay)

The fix correctly set this: var _this; -> var _this = this;

// input
class MyClass {
  myAsyncMethod = async () => {
    console.log(this);
  }
}

// output
class MyClass {
  constructor() {
    var _this = this; // _this wasn't being set to `this`
    this.myAsyncMethod = babelHelpers.asyncToGenerator(function* () {
      console.log(_this);
    });
  }
}

• babel-plugin-transform-react-constant-elements, babel-types
  • #3510 (https://github.com/babel/babel/pull/3510) Make JSXText Immutable. Fixes T7251. (@le0nik)

JSX with text in it was not being hoisted as other constant elements.

// input
var Foo = React.createClass({
  render() {
    return <div>Text</div>; // text wasn't considered constant
  }
});

// output
var _ref = <div>Text</div>;

var Foo = React.createClass({
  render() {
    return _ref;
  }
});
