If you include a.js and run this code:
var myNumber = 42,
myString = "42",
myArray = [41, 42, 43],
myBoolean = true,
myDate = new Date();

console.log(typeof myNumber);
console.log(typeof myString);
console.log(typeof myArray);
console.log(typeof myBoolean);
console.log(typeof myDate);

console.log(myNumber.constructor);
console.log(myString.constructor);
console.log(myArray.constructor);
console.log(myBoolean.constructor);
console.log(myDate.constructor);

if (myArray.constructor == Array) {
console.log("We found an array");
}

Then console.log(myDate.constructor); logs:
null

Running the code without the library logs:
Date()

What is causing this and how can it be overcome?

Hi, I always get an error in IE8 in shivedCreateElement function (https://github.com/termi/ES5-DOM-SHIM/blob/0.7/__SRC/a.ie8.js, l:2115) saying that this["orig__createElement"] is null.
I changed this["orig__createElement"] to document["orig__createElement"] and now it works for me.

MDSN:
getAttribute method
setAttribute method
removeAttribute method

For resolve problems with properties and attributes in IE < 8, we can use second parameter in [get/remove]Attribute and third parameter in setAttribute.

var div = document.createElement("div");
div.testValue = 666;
div.setAttribute("testValue", "lolcat");
console.log("property value: " + div.testValue, " ", "attribute value: " + div.getAttribute("testValue"));

div.testValue = 666;
div.setAttribute("TESTVALUE", "lolcat", 1);
console.log("property value: " + div.testValue, " ", "attribute value: " + div.getAttribute("TESTVALUE", 1));

"node.addEventListener("event", function)" throw Error in FF 3.6
shim doesn't work

Object.getOwnPropertyDescriptor(KeyboardEvent.prototype, "location")

throw Error: Illegal operation on WrappedNative prototype object

Object.getOwnPropertyDescriptor(document.__proto__, "firstChild")

throw Error: Could not convert JavaScript argument

After the first call to this lookupGetter, function Object.getOwnPropertyDescriptor begins to work.

KeyboardEvent.prototype.__lookupGetter__("location");
Object.getOwnPropertyDescriptor(KeyboardEvent.prototype, "location");
document.__proto__.__lookupGetter__("firstChild");
Object.getOwnPropertyDescriptor(document.__proto__, "firstChild");

[].find(function () {}) → undefined

сейчас возвращает -1

defineProperty при попытке добавить свойство remove для HTMLSelectElement.prototype выбрасывает исключение: «can not redefine property».

if your doing an xhr2 shim

please make it a standalone module like with DelegateListener
