Async-await in JS is sometimes used to swallow exceptions. It's very often used to do 1 thing at a time when N things could be done instead. It serializes the execution a lot when it could be concurrent.
if (await is_something_true()) {
// here is_something_true() can be false
}
And above, the most common mistake.
Similar side-effects happen in other languages that have async-await sugar.
It smells as bad as the Zig file interface with intermediate buffers reading/writing to OS buffers until everything is a buffer 10 steps below.
It's fun for small programs but you really have to be very strict to not have it go wrong (performance, correctness).
