      Description

      The void operator evaluates its argument and unconditionally returns undefined. It can be useful in pre-ECMAScript 5 environments, where undefined could be reassigned, but generally, its use makes code harder to understand.

      Noncompliant Code Example

      void doSomething();
      

      Compliant Solution

      doSomething();
      

      Exceptions

      No issue is raised when void 0 is used in place of undefined.

      if (parameter === void 0) {...}
      

      No issue is also raised when void is used before immediately invoked function expressions.

      void (function() {
         ...
      }());
