use createMemo outside a component
is it correct to use createMemo outside a component function? Can I use it in a util file?
The above fn is in a util file. In the above fn
const getDataFromFirebase = (dataToFetch) => {
try {
if (firebaseDetails && Object.keys(firebaseDetails || {})?.length) {
// some operations performed
}
} catch (error) {
}
};The above fn is in a util file. In the above fn
Object.keys(firebaseDetails || {}) is a very heavy computation since firebaseDetails is very large object. I want to memoise this. Is the below implementation correct? Since I am using createMemo outside the component in a util file and getDataFromFirebase is called from many places that's why it is placed in a util file.const memoizedFirebaseKeys = createMemo(() => Object.keys(firebaseDetails || {}));
export const getDataFromFirebase = (dataToFetch) => {
try {
if (firebaseDetails && memoizedFirebaseKeys().length) {
// some heavy computation
}
} catch (error) {
}
};
