Async/await exponential retry

async-await-retry.js

const startTime = Date.now()

const start = async (attempt, { retries = 3, interval = 250 }) => {
  for (let tries = 0, delay = interval; tries < retries; tries++, delay *= 2) {
    console.log('Waiting', delay, Date.now() - startTime)
    await attempt()
    console.log('Retrying!')
  }
  
  console.log('Done trying')
}

const fakeFetch = () => {
  console.log('Fetching something fake')
  
  return new Promise(resolve => setTimeout(resolve, 50))
}

start(fakeFetch, { retries: 3, interval: 250 })
