What are the steps to reproduce this issue? Annotate a call with a tag in the OpenAPI definition. e.g. "- my-tag" Use a custom instance hook. Setup orval to use the custom instance on the specific tag. What happens? The import from useCallback is missing in those generated files. ...
At this time, we put this function inuseCallbackto return, because thedepsis empty, so there is no need to change it, so that when we click theincrease, we won't trigger the subcomponent'srender. How to check The dependency array (deps) will not be passed as a parameter to the cal...
Wrapping the function in useCallback() ensures the function is not recreated, so useEffect() is not triggered to run again. When to use useMemo() If a function includes a complex calculation, you can avoid recomputing it by using the useMemo() hook. This hook returns a memoized value ...

UseCallback is used to optimize the rendering behavior of your React function components, while useMemo is used to memoize expensive functions to avoid having to call them on every render.As a standard construction of hooks, those two solutions are not so different. Like with useEffect, a hook...
useCallbackis easy to use and improves performance. At the same time,useCallbackshould be used only when it is absolutely necessary. It should not be used in every scenario. The general rule is check the performance of the application. if it needs improvement, then we can check whether the...
The second argument to the useCallback function is an empty array []. This means that the handleIncrement function will be memoized and will not change unless its dependencies change. Since we don’t have any dependencies here, it won’t change between renders. ...
