Example with hooks not working

[AshotN]

Following the example using hooks I am getting the follow error

TypeError: showConfirm is not a function

My IDE is also complaining TS2721: Cannot invoke an object which is possibly 'null'

@AshotN as mounting the modal/alert is an async task that is the reason initially value of showConfirm will be null (so the user is aware of it, else calling the function before mounting won't do anything), and once it is mounted it will have a function as the value. So you must check if it's not null before you call it.
