A JavaScript Challenge -- The Array of Randomness

Write a function called deez() which creates and returns an array of random length whose items are random numbers.

Example usage and output:

console.log(deez())
// [0.8029792178993878, 0.9291390188438964]

console.log(deez())
// [0.33210968307150557]

console.log(deez())
// [0.8937903294523319, 0.38640098414032686, 0.758686960140309, 0.3845423409997013]

However, the following constraints MUST be respected:

1. Use only vanilla JavaScript and no other language or framework.
2. Avoid bracket notation (e.g. let ligma = [], squeal[69], !+([])).
3. Avoid prototype/static methods from Array, TypedArray, and their subclasses (e.g. Array.prototype.push(), Int8Array.from()).
4. Avoid any other prototype/static methods that create arrays (e.g. String.prototype.split()).
5. Avoid array constructors (e.g. Array(), Int8Array()).
6. Avoid arrays from JSON (e.g. JSON.parse("[1, 2, 420]")).
7. Avoid arrays from regex results (e.g. "registered\r\nnurse\r\n".match(/(?=(.+))\1/g)).
8. Avoid array-like objects (e.g. arguments, { 0: "Brazil", 1: "mentioned" }).
9. Avoid looping keywords (e.g. for, while, do...while).
10. deez() must not call itself.
11. Avoid using the Y combinator.
12. deez() must be a pure function (aside from random number generation).
13. deez() must produce fresh output every time it is called.
14. deez().length > 0 must always be true.
15. deez().every(Number.isFinite) must always be true.
16. Use dynamically generated randomness, not xkcd randomness.
17. eval() is allowed...
