useEffect(() => {
return history.replace({
pathname: "path/A",
});
}, []);
useEffect(() => {
return history.replace({
pathname: "path/B",
});
}, []);
When the component unmounts, what will be the URL? What determines the order of execution of the above 2 useEffect
?
Due to the nature of you passing no deps
; both of these useEffect
s will only be rendered on component mount. Therefore, the result is (and always will be) "path/B"
.
If you wanted it to change on component unmount, you'd need to add a return
function to one of them.
useEffect(() => {
history.replace({ pathname: "path/B" });
return () => history.replace({ pathname: "path/B" });
}, []);
