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]

TypeScript Support

Hyperapp comes with TypeScript support out-of-the-box. For those unaware, TypeScript is essentially JavaScript with the added precision of static typing, amongst other things. For the remainder of this document we'll assume you have some familiarity setting up and working with TypeScript so we can focus on Hyperapp-specific info.

Preparation

Hyperapp's type definitions take advantage of certain others that come bundled with TypeScript. So, in your project's tsconfig.json be sure to have at a bare minimum:

Suggested Improvements for the Haskell Book v1.0RC4 - Part 1

Note: Page numbers used here are the ones for the "haskell-programming-1.0RC4-screen" version of the book.

Content in question: "Their reviews helped ensure the book is suitable for both beginners and comprehensive."

Critique: This line doesn't appear to be grammatically correct or at the very least it's worded awkwardly.

	// forms. This function is able to merge two such values using the form
	// of the initial value if possible.
	const mergeClasses = (a, b) => {
	if (typeof a === "boolean") {
	return b
	}

	if (typeof a === "string") {
	if (typeof b === "boolean") {
