Snippet for Avoiding the async/await hell medium article

correctuse-example-2.js

async function orderItems() {
  const items = await getCartItems()    // async call
  const noOfItems = items.length
  const promises = []
  for(var i = 0; i < noOfItems; i++) {
    const orderPromise = sendRequest(items[i])    // async call
    promises.push(orderPromise)    // sync call
  }
  await Promise.all(promises)    // async call
}

// Although I prefer it this way 

async function orderItems() {
  const items = await getCartItems()    // async call
  const promises = items.map((item) => sendRequest(item))
  await Promise.all(promises)    // async call
}

async function orderItems() {
  const items = await getCartItems()    // async call
  const promises = items.map((item) => sendRequest(item))
  await Promise.all(promises)    // async call
}

why not this version instead?
If it's to emphasize the sync/async parts, maybe it's worth mentioning that the code can be simplified 😄

Thanks I have updated the gist. However as many devs mentioned on medium, this method has certain disadvantages like if the number of items is way too large, we'll incur huge cost for context switching

this is a cool solution @itaditya, I'm going to fork this gist!
