I think `for element of list` nowadays starts to become a realistic choice (without a transpiler) for that: https://caniuse.com/?search=for...of

As an added benefit, `for...of` works with async, unlike forEach.

If I would be tempted to use forEach but can’t because async, I usually don’t want for…of semantics, though. I probably want something like
await Promise.all(collection.map(thing => some_async_function(thing)));
for thing of collection {
await some_async_function(thing);
}
