Code Inspection: Void function return value used

Reports a return value of a function that doesn't return anything. Calling of such functions always produces an undefined value and such assignment may indicate an error.


let a = console.log('foo');

The following usages are ignored:

  • Inside a return statement

  • In some binary operations

  • For overridden non-void functions

Suppress an inspection in the editor
