Arrow function easier

1 - normal function

let execute = function(n) {
  return n*n;
}

let x = execute(5)
console.log(x)

// Output:
// 25

---

2 - arrow

let execute = (n) => {
  return n * n;
};

let x = execute(5);
console.log(x);

---

3 - arrow without return

• If arrow function body has one statement then, {} not needed

let execute = (n) => n * n;

let x = execute(5);
console.log(x);
