Is it worth taking data from data parameters?

Question

React

Tell me, as far as I understand, it is highly undesirable to pass event handlers to components that will be created anew each time, that is, onClick={() => action()}.
It is correct to move the handler to a variable and then it will not be created anew each time.
Then the question arises, how can you pass data to the parent component? onClick={() => props.handler(data)} can't be done anymore. Somewhere I saw an option to leave the data in the data attributes, and in the handler to take them from there.
To what extent is this practice necessary or are these already unnecessary troubles, and this problem is far-fetched?
