Excessive range check

Reports condition chains in which a value range is checked and these condition chains can be simplified to a single check.

The quick-fix replaces a condition chain with a simplified expression:


x > 2 && x < 4

After the quick-fix is applied:

x == 3


arr.length == 0 || arr.length > 1

After the quick-fix is applied:

arr.length != 1
