What is the (function() { } )() construct in JavaScript?

Question

Can anyone help me understand the below function definition in JavaScript?

(function () {

})();

Any help would be appreciated.

Answer 1

Basically, it is defined as an immediately-invoked function expression that is going to be executed immediately whenever it got created. You can use the below code snippet to use IIFE:

((foo) => {

 // do something with foo here foo

})('foo value')

I hope this will help.
