pregen-stash

---

FIFO data structure that serves you with pregenerated values from your custom computation-intensive function. Getting those pregenerated values then boils down to a cheap Array.prototype.pop.

---

Get it!

npm install --save pregen-stash

Usage

const createStash = require('pregen-stash')
 
createStash(5, Math.random)
  .then(stash => {
    for (var i = 0; i < 13; i++) console.log(stash.pop(), stash.size)
  })
  .catch(console.error)
