v1.6.2

Release date: April 15th, 2021

  • 'typings' field updated in package.json file (See issue #86).

v1.6.1

Release date: September 18th, 2018

  • Fixed a bug in Reflect.construct where, if the optional newTarget argument was passed, the shim would call the newTarget constructor function rather than the target constructor (See issue #81).

v1.6.0

Release date: February 22nd, 2017

  • The Reflect global is no longer blindly overridden. If Reflect global exists when this library is loaded, all standard Reflect methods are overridden with this shim's implementations, but any other methods defined on the Reflect global are left intact (See issue #79).

v1.5.1

Release date: December 23rd, 2016

  • package.json file now contains license field with SPDX expression.

v1.5.0

Release date: August 17th, 2016

  • Added missing proxy invariant checks in getOwnPropertyDescriptor, defineProperty and deleteProperty traps.
  • Add typings for Reflect for TypeScript users.

v1.4.6

Release date: April 19th, 2016

  • ES6 Object.assign(...args) would fail when one of the arguments is a Proxy object. Patched Object.assign to fall back on an ES5 shim when at least one of the arguments is a Proxy object (See issue #72).

v1.4.5

Release date: April 5th, 2016

  • Patched Object.getOwnPropertySymbols(proxy) to always return [] (only if the ES6 global Object.getOwnPropertySymbols exists). Symbols are not supported by this shim, but at least this patch stops code that tries to get the own symbol-valued properties of a proxy from crashing. (See issue #71).

v1.4.4

Release date: March 19th, 2016

  • Minor bugfix in Reflect.construct().
  • Removed deprecation notice when unpatched Object.getOwnPropertyNames(proxy) used in external modules would still trigger the old getOwnPropertyNames trap (See issue #66).

v1.4.3

Release date: March 17th, 2016

  • Reflect.construct() now works on ES6 classes (See issue #69).
  • The patched __proto__ set accessor now converts the argument prototype to an Object. This fixes issue #67 (tab-completion in node.js no longer crashes when this module is loaded).

v1.4.2

Release date: August 30th, 2015

  • This library now leaves the Proxy global untouched (rather than overwriting it with a dummy function) if it exists but does not implement the old Proxy API (such as IE Edge). See issue #59.
  • Clarified incompatibility of this library with ES6 Symbols in the README.

v1.4.0

Release date: July 2nd, 2015

  • The patched Proxy object exported by this library now leaves the old Proxy.create and Proxy.createFunction untouched, so old code that needs it can still use it. Also, this makes the library robust against multiple versions of itself being loaded. See issue #56.

v1.3.1

Release date: June 21st, 2015

  • The Proxy object is only patched if Proxy.create exists.

v1.3.0

Release date: May 28th, 2015

New features:

  • Object.defineProperties is patched and will trigger the defineProperty trap when called on a proxy. See issue #51.

Bugfixes:

  • Object.defineProperty(o,p,desc) now returns o (as per ES5 spec) rather than a boolean success value.

v1.2.1

Release date: May 20th, 2015

Minor changes:

  • Calling the unpatched, native Object.getOwnPropertyNames method on a proxy now redirects to that proxy's ownKeys trap rather than failing with a TypeError. See issue #48.

v1.2.0

Release date: May 11th, 2015

  • Reflect.construct now takes third optional newTarget parameter, as per ES6 draft April 3, 2015.

v1.1.2

Release date: march 13th, 2015

Minor bugfix:

  • delete now works on a proxy for a proxy (issue #46)

v1.1.1

Release date: november 14th, 2014

Minor bugfixes:

  • Reflect.enumerate(aProxy) now works as intended (issue #43)
  • Patched Object.freeze(obj) now returns obj rather than a boolean (issue #42)

v1.1.0

Release date: august 29th, 2014

Improved compliance with August 24, 2014 (Rev 27) ECMAScript 6th edition draft standard.

  • Removed Reflect.getOwnPropertyNames and the getOwnPropertyNames proxy trap. Use Reflect.ownKeys and the ownKeys trap instead.
  • Reflect.ownKeys now returns an array of strings (rather than an ES6 iterator)
  • ownKeys trap now checks various invariants previously checked by the getOwnPropertyNames trap.
  • Object.keys(proxy) now triggers ownKeys trap, which checks invariants, so the result of Object.keys(proxy) is again reliable.

v1.0.0

Warning: this version contains multiple backwards-incompatible changes compared to v0.0.13 to improve compatibility with the final ES6 spec. Changes compared to v0.0.13:

  • Improved compliance with May 22 ECMAScript 6th edition draft standard.
  • Removed deprecated Reflect methods and corresponding Proxy traps:
    • Reflect.hasOwn
    • Reflect.keys
    • Reflect.freeze
    • Reflect.seal
    • Reflect.isFrozen
    • Reflect.isSealed
    • Reflect.iterate
  • Reflect.getOwnPropertyNames no longer marked deprecated (not yet reflected in the May 22 draft, but [[GetOwnPropertyNames]] should return as a built-in operation on objects and proxies).
  • Reflect.enumerate and the enumerate trap now return an ES6 iterator rather than an array.
  • Reflect.ownKeys iterator uses new ES6 iterator protocol (next/done/value rather than next/StopIteration API).
  • Removed Reflect.Proxy. Use the global Proxy instead.
