Unused assignment

Reports the cases where a variable is redundant as its value is never used after its assignment.

If the variable is unused, we recommend removing it to shorten the code and to avoid redundant allocations.

The following cases are reported:

• the variable never gets read after assignment

• the value is always overwritten with another assignment before the next variable read

• the variable initializer is redundant (for one of the above two reasons)
