A helpful note on a lesson learned with combining async/await with .map

https://stackoverflow.com/questions/40140149/use-async-await-with-array-map/40140562#40140562

Problem: If you give await an object that isn't a Promise (like what .map returns), then it'll evaluate immediately instead of actually waiting.

Solution: Wrap the .map in Promise.all, like this: await Promise.all(arr.map(async x => await someProcessing(x)))
