You should use forEach in JavaScript, except for when you must use for, except for when you want to reveal hidden, non-enumerable items... ugh.

Do a whole series on promises.
Would love to see a video on the gotchas and the misconceptions of how promises behave (read: _actually_ work) in a loop (e.g. for, forEach, map, etc.).
I'm talking specifically about trying to use promises in the loop's executing statement.

You can use await with a "for of" loop
for(const el of array) await el;
