arrow function

hello = () => {
  return "Hello World!";
} 

// Traditional Function
function (a){
  return a + 100;
}

// Arrow Function Break Down

// 1. Remove the word "function" and place arrow between the argument and opening body bracket
(a) => {
  return a + 100;
}

// 2. Remove the body brackets and word "return" -- the return is implied.
(a) => a + 100;

// 3. Remove the argument parentheses
a => a + 100;

// Traditional Function
function bob (a){
  return a + 100;
}

// Arrow Function
let bob = a => a + 100;

Arrow Function is another way to write a function.
"classic method":
function x ()
{
	console.log("X")
}
"arrow method":
var x= ()=>
{
	console.log("X")
}
if we need to add paramiter is pritty simple:
var x = (PARAMS) =>
{
	console.log(PARAMS)
}
Have a nice day
