Result of increment or decrement used

Last modified: 03 December 2024

Reports an increment (++) or decrement (--) expression where the result of the assignment is used in a containing expression. Such assignments can result in confusion due to the order of operations, as evaluation of the assignment may affect the outer expression in unexpected ways. Example: var a = b++
