we don't want to call setState after unmount.

[unworthyEnzyme]

Description

We should cleanup all the async tasks after react unmounts the component otherwise this can potentially cause a memory leak.

Additional context

I am not sure if this is a right solution in the case of react code. We could use a cancel token with useRef but this solution seemed more framework agnostic.
