Arrow function in JavaScript

There’s an alternative way of writing anonymous functions, which we call an arrow function. An arrow function uses () => instead of function ():

function using function ();

document.querySelector("html").addEventListener("click", function () {
  alert("Ouch! Stop poking me!");
});

function using arrow function;

document.querySelector("html").addEventListener("click", () => {
  alert("Ouch! Stop poking me!");
});
