Can you offer a use case for the new arrow = function syntax?

Arrow functions provide a concise syntax for writing functions in JavaScript. They are particularly useful for maintaining the this context within methods and callbacks. For example, in an event handler or array method like map, arrow functions can simplify the code and avoid issues with this binding.

const numbers = [1, 2, 3];
const doubled = numbers.map((n) => n * 2);
console.log(doubled); // [2, 4, 6]
