I am trying to set up authentication in my Next.js 14 app using the App Router. What is the best approach for handling user sessions and protecting routes?
Great question! You can use the Array.map() method to transform each element. Here's a simple example: const numbers = [1, 2, 3, 4, 5]; const doubled = numbers.map(num => num * 2); console.log(doubled); // [2, 4, 6, 8, 10] The map() method creates a new array by applying a function to every element in the original array.

Another approach would be using forEach() if you need to perform side effects: const numbers = [1, 2, 3]; numbers.forEach(num => { console.log(num * 2); }); But remember, forEach() doesn't return a new array, while map() does. So choose based on your use case.
