It was not my intention to discourage, sorry if it felt that way. But for having such a strong title, I felt the post was lacking information, that's all. No need to get angry or discouraged by this, I was hoping for a bit of a conversation about this.
Just read the hook documentation
I've checked the docs, and found not much information about why this particular example is more optimized, that's why I asked! Also, by the title I supposed this post would explain that in detail...
Again, I'm sorry if I sounded harsh or discouring. That's not my intention at all, but I hate these kinds of titles, even more if they don't offer that much value.
I understand. There is a great explanation on why you should use it in a previous post I wrote, using websockets with React.js. I explained in detail how use Callback saved my life there.
Check Kent C. Dodds article if you still not get it, (I'll just copy some part of it here below)
Q: So when should I useMemo and useCallback?
A: There are specific reasons both of these hooks are built-into React:
Referential equality
Computationally expensive calculations
And thanks for the article @itays123
, hope it can cover more complex cases and explanation in the future so some readers won't get the wrong idea of this hook, because premature code optimization can lead them to make thing worse
Just read the hook documentation. I'm sure you have better things to do other than commenting discouraging comments on random posts.

Fantastic I'll check that out too, thanks for the info
Yup, totally agree here, that was in part why I wanted to understand it better
Already Archived and prepating a better one
