Usage

import * as mod from "https://git.sr.ht/~ruivieira/deno-experiments/blob/master/randomjs/mod.ts";

§Classes

MersenneTwister19937	An Engine that is a pseudorandom number generator using the Mersenne Twister algorithm based on the prime 2**19937 − 1
Random	A wrapper around an Engine that provides easy-to-use methods for producing values based on known distributions

§Variables

browserCrypto	An Engine that relies on the globally-available `crypto.getRandomValues`, which is typically available in modern browsers.
nativeMath	An int32-producing Engine that uses `Math.random()`

§Functions

bool	Returns a boolean Distribution with 50% probability of being true or false
createEntropy	Returns an array of random int32 values, based on current time and a random number engine
date	Returns a Distribution that returns a random `Date` within the inclusive range of [`start`, `end`].
dice	Returns a distribution that returns an array of length `dieCount` of values within [1, `sideCount`]
die	Returns a Distribution to return a value within [1, sideCount]
hex	Returns a Distribution that returns a random string comprised of numbers or the characters `abcdef` (or `ABCDEF`) of length `length`.
int32	Returns a value within [-0x80000000, 0x7fffffff]
int53	Returns a value within [-0x20000000000000, 0x1fffffffffffff]
int53Full	Returns a value within [-0x20000000000000, 0x20000000000000]
integer	Returns a Distribution to return a value within [min, max]
pick	Returns a random value within the provided `source` within the sliced bounds of `begin` and `end`.
picker	Returns a Distribution to random value within the provided `source` within the sliced bounds of `begin` and `end`.
real	Returns a floating-point value within [min, max) or [min, max]
realZeroToOneExclusive	Returns a floating-point value within [0.0, 1.0)
realZeroToOneInclusive	Returns a floating-point value within [0.0, 1.0]
sample	From the population array, produce an array with sampleSize elements that are randomly chosen without repeats.
shuffle	Shuffles an array in-place
string	Returns a distribution that returns a random string using numbers, uppercase and lowercase letters, `_`, and `-` of length `length`.
uint32	Returns a value within [0, 0xffffffff]
uint53	Returns a value within [0, 0x1fffffffffffff]
uint53Full	Returns a value within [0, 0x20000000000000]
uuid4	Returns a Universally Unique Identifier Version 4.

§Interfaces

Engine

A mechanism to retrieve random int32 values

§Type Aliases

Distribution	A function to use an `Engine` to produce a value
StringDistribution	A function to use an `Engine` to produce a string of a requested length
