This is what is used:
useEffect(callback[, dependencies]);
Why does the square brakets begin with a coma? I my mind , I have something like this:
useEffect(callback, [dependencies]);
Thanks for your explanations.

3Where are you seeing the first example used or recommended? It's syntactically incorrect. The second is correct – Brian Thompson Sep 09 '22 at 18:00

@GiorgiMoniava Yes. It's clear now. Thanks. – Zen Sep 09 '22 at 19:19

@BrianThompson it's a common syntax for documentation used on many sites like mdn. The second syntax would suggest that adding a trailing comma is ok. – Konrad Sep 09 '22 at 19:42

I didn't see any indication that it was talking about documentation, but that would make sense. – Brian Thompson Sep 09 '22 at 19:46
