js arrow function
//If body has single statement
let myFunction = (arg1, arg2, ...argN) => expression
//for multiple statement
let myFunction = (arg1, arg2, ...argN) => {
statement(s)
}
//example
let hello = (arg1,arg2) => "Hello " + arg1 + " Welcome To "+ arg2;
console.log(hello("User","Grepper"))
//Start checking js code on chrome inspect option// 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
)
const suma = (num1, num2) => num1+num2
console.log(suma(2,3));
//5hello = () => {
return "Hello World!";
}// 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; };hello = () => {
return "Hi All";
