TypeError: Object(...) is not a function reactjs
It looks fine, you just have to export
your function that's it.
use
export let fillCalendar = (month, year) => {
instead of
let fillCalendar = (month, year) => {
Just putting it out there....
I saw this error because I imported a function from the wrong module!
But I'm sure you'd never do that ;-)
(obviously a bit unlucky in that the function I imported had a common name - useParams
in my case)
In addition to the accepted answer, I have observed that this error more generally occurs when the module/object being imported doesn't exist. I experienced it while trying to import a component of a library that had since removed the component. In my case, the specific component was FirebaseRealTimeSaga
that is no longer available in the React Admin Firebase package
