There are different structure of create function in node.js. Like :
function abc(){
console.log('stackoverflow');
}
Is there any new format available and is it usefull?

2Your question suggests lack of research. Node.js relies on JavaScript, all syntax was inherited from it.E_net4– E_net42016-09-09 10:17:16 +00:00Commented Sep 9, 2016 at 10:17

Method#1
function test(){}; // function declaration
Method#2
var test = function(){}; // function expression
Method#3
var abc = function test(){}; // named function expression

var test = (function(){ // IIFE that returns a function
return function(){}
})();

var Test = new Function(); // Function constructor
Method#6
var Test = a => a * 2; // ES6 arrow function

That is the format till EcmaScript 6.
Then, to declare a function, you can use:
let result = abc => console.log('stackoverflow');
