Example 1: js arrow function

// const add = function(x,y) {
//     return x + y;
// }

// const add = (x, y) => {
//     return x + y;
// }

const add = (a, b) => a + b;


const square = num => {
    return num * num;
}

// const rollDie = () => {
//     return Math.floor(Math.random() * 6) + 1
// }

const rollDie = () => (
    Math.floor(Math.random() * 6) + 1
)

Example 2: arrow function

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)
}
