What is an arrow function

An arrow function is a concise way to write function expressions in JavaScript. Introduced in ES6 (ECMAScript 2015), they provide a more succinct syntax compared to traditional function expressions. Arrow functions do not bind their own `this`, making them particularly useful for certain scenarios, such as in callbacks or methods that rely on the context of the surrounding code.

const sum = (a, b) => a + b;
console.log(sum(5, 3)); // Output: 8
