merry-go-round

Round robin proxy for iterating over arrays.

Install

npm install @amscotti/merry-go-round

Usage

import { createRoundRobin } from '@amscotti/merry-go-round'

const items = [{
  name: 'Alice',
  greet() {
    return `Hello, ${this.name}` 
  }
}, {
  name: 'Bob',
  greet() {
    return `Hi, ${this.name}`
  }
}]

const proxy = createRoundRobin(items)

proxy.greet() // 'Hello, Alice!' 
proxy.greet() // 'Hi, Bob!'
proxy.greet() // 'Hello, Alice!'

createRoundRobin takes an array and returns a Proxy that rotates over the items, exposing their properties and methods.

This allows iterating over an array in a round robin manner easily.

API
