what is arrow function code example

Example 1: javascript arrow function

// Non Arrow (standard way)
let add = function(x,y) {
  return x + y;
}
console.log(add(10,20)); // 30

// Arrow style
let add = (x,y) => x + y;
console.log(add(10,20)); // 30;

// You can still encapsulate
let add = (x, y) => { return x + y; };

Example 2: arrow function javascript

const suma = (num1, num2) => num1+num2
console.log(suma(2,3));
//5

Example 3: javascript arrow function

let errow = () => {
  //the code you want to return;
};
Or
let errow = ('paramiter') => {
//the code you want to return
}

Example 4: arrow function

// 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;

Example 5: js arrow function

hello = () => {
	return "Hi All";
}

Example 6: 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)
}
