randomSeeded

A linear-congruential generator: it returns a function that produces deterministic floats in [0, 1). Pass that function as the generator argument to randomBetween / chance for reproducible runs — tests, fixtures, replays. Part of pota/use/random.

Arguments

Argument	Type	Description
seed	number	Seed for the generator's sequence.

Returns: () => number — a generator producing deterministic floats in [0, 1). The same seed always yields the same sequence.

Examples

Reproducible randomness

Seeds the generator and feeds it to randomBetween — the same seed replays the identical sequence across runs.

import { randomSeeded, randomBetween } from 'pota/use/random'

const rng = randomSeeded(42)
randomBetween(0, 9, rng) // deterministic across runs
