deep-random-pick/src/shallowpick.ts

Picks a pseudo-random item from a pool in several ways, including a recursive method that allows for more control over probability.

import { arrayPick } from './arrayPick';

export const shallowPick = (...pool) => {
    if (pool.length > 1) {
        return arrayPick(pool);
    } else {
        return arrayPick(pool[0]);
    }
}
