By default, the surface comparison function is used in createSelector. Want to make a deep comparison, use createSelectorCreator and your comparison function. There is an example in the documentation.
I try to reselect and immediately got up the problem: data polling works. Almost every time the same data arrives in the reducer — a component rerender occurs using this data. I try to cache this data with the selector — fails — the rerender still happens. What is wrong with this code?
function getAllTickets(reducer) {
return reducer.get('tickets');
}
export const allTicketsSelector = createSelector([getAllTickets], items => items);
