JavaScript Array Methods vs Loops

What are the main differences between using array methods and loops in JavaScript?

Array methods like map, filter, and reduce are often more concise and expressive than traditional loops. They can make your code cleaner and easier to read.

Can you give me an example of using map versus a for loop?

Sure! Using map: const doubled = arr.map(num => num * 2); vs. a for loop: for (let i = 0; i < arr.length; i++) { doubled.push(arr[i] * 2); }.

When should I prefer one over the other?

Use array methods for cleaner, more readable code when working with arrays. Use loops for more complex logic or when performance is critical.

Are there any performance differences I should be aware of?

Yes, array methods can be slower than loops for large datasets due to function calls. Always consider the context of your application.
