This is my code block looks line when used with a useCallback hook in react but I want to use same function in svelte,but want to add this in useCallback hook. Is there any alternative for svelte.
const newCancelToken = useCallback(() => {
axiosSource.current = axios.CancelToken.source();
return axiosSource.current.token;
}, []);
Keep that in mind: The way svelte processes its components is very different from react.
React re-renders all components any time any state within a component, or anywhere in a parent, changes. To avoid the re-computation you will need the use of useMemo or useCallback in your case.
Svelte is a compiler and analyzes your template to create targeted DOM update code whenever any concerned state changes. With that in mind, you don't need to memoize such functions with svelte.
