What happens when I execute several fetch at the same time?
Does each fetch run completely separately and one fetch doesn't have to wait for another to finish?
Or are all the fetch somehow "linked"?
Let us take a concrete example: - I execute two fetch at the same time, one that calls an API and asks to retrieve information and the other one that calls another API but this one has a 'long response time' (so the fetch will run for a long time). Can the second fetch influence the response time of the first fetch?
