How & why

Each produced value is a modulo 1 of the sum of the previous value (or a seed) and the golden ratio. Values are uniformly distributed but appear in a predictable repeatable pattern where neighbor values can't appear one after another. This can be used for generating a diverse set of values, for example we can use generated values for hue in HSL for generating colors. Compare it to a plain Math.random():

element.style.backgroundColor = `hsl(${Math.round(randomValue * 360)}, 83%, 71%)`;

API

createGenerator(seed?: number): () => number

Create Golden ratio based number generator function.

Returns a function that will return a new number on each call.

• seed - A float number between 0 and 1. Default is a random number from Math.random()
