IIFE :more IIEF

Immediately Invoked Function Expressions (IIFE) are JavaScript functions that are executed immediately after they are defined. They are typically used to create a local scope for variables to prevent them from polluting the global scope.

syntx :
(function (){
// Function Logic Here.
})();
Ex :
(function() {
// IIFE code block
var localVar = 'This is a local variable';
console.log(localVar); // Output: This is a local variable
})();
