sindresorhus/unique-random: Generate random numbers that are consecutively unique

Generate random numbers that are consecutively unique

Useful for things like slideshows where you don't want to have the same slide twice in a row.

npm install unique-random

import {consecutiveUniqueRandom} from 'unique-random';

const random = consecutiveUniqueRandom(1, 10);

console.log(random(), random(), random());
//=> 5 2 6

Generate random numbers that are consecutively unique, meaning that each number in the sequence is distinct from the one immediately before it.

Generate random numbers that do not repeat until the entire range has appeared.

Returns a function, that when called, will return the generated number.

The returned function is also an iterable which consumes from the same source as the function:

import {exhaustiveUniqueRandom} from 'unique-random';

const random = exhaustiveUniqueRandom(1, 10);

for (const number of random) {
	console.log(number);

	// The unique numbers will be iterated over infinitely
	if (stopCondition) {
		break;
	}
}

Note

If minimum is equal to maximum, the same value will always be returned.
