Achievement unlocked: today, for the first time, I wrote an asynchronous iterator. Using an async generator (also for the first time; I never felt a need for them before), nothing as fancy as writing it completely from scratch as an object with Symbol.asyncIterator. I wanted to transform an array of strings into a chain of sequentially executed promises. Previously, I would have used a .reduce starting with a Promise.resolve(). But this time, I tried the async generator syntax, and it seems to have worked beautifully.
