design patternsIIFE

IIFE - Iimmediatelly Invoked Function Expression

var foo = "foo1";


(function () {
  var foo = "foo2";
  console.log(foo); // foo2
})();


console.log(foo); // foo1


// we can also write the above statement like:
(function () {
  // code
})();

We use IIFE in order to not pollute the global scope.
