/**
Normalize-1.1.2.js: A collection of polyfills to standardize the JavaScript browser environment.
Examples: window.console.log, Object.is() / keys(), String.prototype.trim() / fromCodePoint(),
Array.prototype.every() / forEach() / map() / sort(), etc.
https://www.ecma-international.org/ecma-262/11.0/
Adapted and extended from es5-shim.js
Polyfix: A concatenation of 'polyfill' and 'bugfix'.
Many snippets of code here are simultaneously both polyfills and bugfixes.
Polyfill Order:
General
Window
Number
Math
Array
Object
String
Regexp
Date
JSON
*Event (slated for 2.0)
*Document (slated for 2.0);
I have cleaned up a lot of the superfluous code logic present in ES5-shim.js.
There might be a slight performance cost (<1 to 10)% compared to ES5-shim.js, on legacy engines,
but the gain is in filesize.
This cost will be indistinguishable on modern engines, which are exponentially faster, and which will have
many native functions defined already.
Runs on IE9+, Safari 3.2+, Chrome, Firefox, etc.
Keylog:
`#` : Edited for formatting, code logic, or cross-browser support, or when I am the author
`...` : marked as unneccesary or very highly unlikely that you would need to polyfill.
`!!` : Want to polyfill, needs polyfill.
Note 1:
Certain Array.prototype methods, if required to be polyfixed,
if 'use strict' is unsupported,
will necessarily not throw a TypeError if called on null or undefined,
different from the native functions, due to null / undefined being replaced
with the global object in non-strict mode `call`
and it being impossible to determine if
the function was called with null, undefined or window
