- s_y_n_t_a_x 7y agoNot all functions needs hooks, not all hooks break pureness. But my point was functions are simpler in all those scenarios, pure or not. Edited my comment to reflect that.
- csande17 7y ago> not all hooks break pureness Sure, if you define a function called useWhatever that doesn't actually call any hooks, that might be a pure function. But the restrictions described in https://reactjs.org/docs/hooks-rules.html https://reactjs.org/docs/hooks-rules.html are not restrictions that pure functions have.
