Rule: Avoid use of constructor functions for side-effects

• Title
  Avoid use of constructor functions for side-effects

• Description
  Some people like to call constructor functions without assigning its result to any variable:

  var something = new MyConstructor();  //Compliant
  new MyConstructor();   //Non-Compliant, do we call a constructor to get a side effect ? If this is the case, this is definitely misleading.
  

  There is no advantage in this approach over simply calling MyConstructor since the object that the operator new creates isn't used anywhere. So such kind of syntax is misleading and should be avoided.

• Violation message
  Replace the statement by a standard call to the MyConstructor() function

• Default severity
  Major
