When the keyword ``++this++`` is used outside of an object, it refers to the global ``++this++`` object, which is the same thing as the ``++window++`` object in a standard web page. Such uses could be confusing to maintainers. Instead, simply drop the ``++this++``, or replace it with ``++window++``; it will have the same effect and be more readable.


== Noncompliant Code Example

----
this.foo = 1;   // Noncompliant
console.log(this.foo); // Noncompliant

function MyObj() { 
  this.foo = 1; // Compliant 
} 

MyObj.func1 = function() { 
  if (this.foo == 1) { // Compliant
    // ... 
  } 
} 
----


== Compliant Solution

----
foo = 1;               
console.log(foo);

function MyObj() { 
  this.foo = 1;  
} 

MyObj.func1 = function() { 
  if (this.foo == 1) {
    // ... 
  } 
}
