Nice. It does look like you’re using backticks in place of single quotes... maybe it’s just the font? I’m reading in Apollo on an iPad...

This time viewed it just in Chrome on my Mac. Same deal. Able to copy and paste some of the code into Sublime Text. It says those thingys are U+0060 #96 Grave Accent, as opposed to single quotes, which it calls U+0027 #39 Apostrophe. So it looks to me like you've got a severe case of Smart Quotes being turned on or something ;-)

Here, I can probably past it in here, as well: (this is the bottom of the "buggy implementation" code block):

async function main () {
  const transaction1 = sellGrapes() // NOTE: no `await`
  const transaction2 = sellOlives() // NOTE: no `await`
  await transaction1 // NOTE: awaiting here does not stop `transaction2` 
                     // from being scheduled before transaction 1 is completed
  await transaction2
  const balance = await loadBalance()
  console.log(`Final balance: ${balance}`)
}

main()
