infinite-random-list

An infinite list of shuffled elements ∞

Takes a reference set of items , returns a random item from this array, infinitely. Never pass 2 identical items in a row.

• non-deterministic
• goes through a full set before shuffling again
• will slice() the given array

Useful for generating an infinite grid based on different patterns/positions, or showing random informations without showing the same item multiple times.

Installation 📦

npm i infinite-random-list -S

Usage & example 💾

    import InfiniteRandomList from 'infinite-random-list'

    let list = new InfiniteRandomList(['Emma', 'Hannah', 'Alex', 'Mia'])
    list.get() // 'Alex'
    list.get() // 'Mia'
    list.get() // 'Emma'
    list.get() // 'Hannah'
    // shuffles again here
    list.get() // 'Mia'
    list.get() // 'Alex'
    ...

• new InfiniteRandomList(items) Returns a list instance populated with items.

• list.set(items) Sets items (Array) as the reference items.

• list.get() Returns one item from the original set (passed using list.set(items) or the constructor). Always returns something (i.e. the list doesn't get empty). Always return a different item.
