reactjs - ComponentWillMount / componentWillUnmount order after RN 0.43.4 -


this question contributors of react native or know underlying library well. there doesn't seem discussion on github can follow, brought here.

in release notes of 0.43.4, there change called "switch componentwillmount / componentwillunmount order". explain me mean "componentwillmount happens before componentwillunmount when child switches"?

from understanding of react lifecycle, componentwillmount happens before componentwillunmount, when child switches part confusing me.
