Can we say that it is IIFE?!? - In Javascript

Question

As you know in Javascript, the following expression is very often used as IIFE ( I immediately I nvoked F unaction E ):

(function(){
  //code ...
})();

I wonder if we can say that the following expression is IIFE (when no return value is required):

new function(){
 //code ...
}

Or

new function(global){
  //code..
}(this);

Even if it is an object. Thank.
