But in ordinary JS there just can't be a race condition, everything is single threaded.

You can definitely have a race condition in JS. Being single-threaded means you don't have parallelism, but you still have concurrency, and that's enough to have race conditions. For example you might have some code that behaves differently depending on which promise resolves first.
And it doesn't actually prevent concurrency.
Sure, but concurrent != parallel. You can't have data races with a single thread of execution - a while loop writing i=0 or i=1 on each iteration is not a data race.
Two async functions doing so is not a data race either.
You should really look up the definition of race condition; it has nothing to do with parallel processing. Parallel processing just makes it harder to deal with.
Data race != Race condition
