In v1.1.0, there is a new property called threshold in InfiniteScroll. Since InfiniteScroll is implemented with IntersectionObserver, is is easy to implement the threshold functionality. The only thing that is different with IntersectionObserver is InfiniteScroll does not allow passing number array to threshold.
The reason why InfiniteScroll does not allow passing number array to threshold is that I think it is weird. Normally you will set the loading status to be true when your application is going to load data. If you pass the loading status to isLoading, then InfiniteScroll will not call next because you tell it that you are loading data.
That is, although you pass an array like [0.25, 0.5, 0.75, 1], the next will be called only once. As a result, it will not work as expected.
If you think that supporting number array is necessary, you can make an issue with why it is necessary. I will implement the functionality if I think you are right.
I'm trying to learn Jest in order to test this package. So before the next time I release a new version, I am going to add some test to this package.
See you next time!
