Function and Arrow Function Different using Node Js

In this tutorial will teach you what is the Different between Function and Arrow Function. This is very impotent one.
if you want to be a mastering in Node Js.

Normally Create the function this way

function myTest1()   // Function Name
{
    console.log("test function work")
}
myTest1();  // Print the Function

Create the function pass the parameters  without datatype in Javascript

function myTest(name,course,age)  // Create the function pass the parameters
{
    console.log(name);
    console.log(course);
    console.log(age);
}
myTest("John","NodeJs","35");   // Print the Function

Create the function assign to the variable

var myTestfn =  function myTest(name,course,age) //assign to the variable myTestfn 
{
    console.log(name);
    console.log(course);
    console.log(age);
}
myTestfn ("Peter","NodeJs","35"); //Print the variable

Now lets convert the function into Arrow Function

look at this line of the code    var myTestfn = function myTest(name,course,age)

Remove function keyword and function name myTest and put the => arrow

var mynewTest = (name,course,age) =>

var mynewTest = (name,course,age) =>   
{
    console.log(name);
    console.log(course);
    console.log(age);
}
mynewTest("Peter","Java","25");
