Redundant local variable
Reports an unnecessary local variable that does not make a function more comprehensible:
a local variable that is immediately returned
a local variable that is immediately assigned to another variable and is not used anymore
a local variable that always has the same value as another local variable or parameter.
Locating this inspection
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
UnnecessaryLocalVariableJS- Via Settings dialog
Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
Use the checkbox below to have this inspection ignore variables that are immediately returned or thrown. Some coding styles suggest using such variables for clarity and ease of debugging.
