gopd

Object.getOwnPropertyDescriptor, but accounts for IE's broken implementation.

Usage

var gOPD = require('gopd');
var assert = require('assert');

if (gOPD) {
    assert.equal(typeof gOPD, 'function', 'descriptors supported');
    // use gOPD like Object.getOwnPropertyDescriptor here
} else {
    assert.ok(!gOPD, 'descriptors not supported');
}
