Closed

Summary:

Increase the readability of CustomLineHeightSpan by making the logic less stateful.

This is a minor improvement in the context of my multi-PR work on react-native-community/discussions-and-proposals#695.

Changelog:

[INTERNAL] [CHANGED] - Increase the readability of CustomLineHeightSpan

Test Plan:

  • Prove the equivalence of the old and the new logic
  • Test that the behavior of lineHeight doesn't change

...by making the logic less stateful.

Well, as I look at it now, the (int) conversion could be put inside the parens for literal 1:1 equivalence
