I really liked Jordan Harband's suggestion
<https://esdiscuss.org/topic/array-prototype-change-was-tostringtag-spoofing-for-null-and-undefined#content-12>
of
adding Array.empty, Function.empty, etc. to ES7. It is relatively easy to
polyfill as well.
```js
[Array,
ArrayBuffer,
Int8Array,
Int16Array,
Int32Array,
Uint8Array,
Uint8ClampedArray,
Uint16Array,
Uint32Array,
Float32Array,
Float64Array]
.map(T => [T, new T(0)])
.concat([
[Object, {}],
[String, ''],
[RegExp, /(?:)/],
[Function, function () {}],
[GeneratorFunction, function* () {}]
])
.forEach(([root, empty]) =>
Object.defineProperty(root, 'empty', {
value: Object.freeze(empty),
configurable: true,
enumerable: false,
writable: false
}));
```
The code effectively explains what I think would make suitable replacements
for each. I don't see the use cases for some of these, though, such as
`String.empty` or `RegExp.empty`.
