Array Methods vs Loops: Which is Better?

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

Array methods like map, filter, and reduce are higher-level abstractions that can make your code cleaner and more readable. Loops, on the other hand, provide more control and can be more efficient in certain scenarios.

Can you give me an example of when to use an array method instead of a loop?

Sure! If you want to create a new array by transforming each element, using the map method is ideal. For instance, const doubled = arr.map(num => num * 2); is more concise than using a loop.

Are there performance differences between them?

Yes, in some cases, loops can be faster because they avoid the overhead of function calls. However, for most applications, the difference is negligible, and readability often takes precedence.

What about readability? Which one is easier to understand?

Array methods generally enhance readability, especially for those familiar with functional programming concepts. They express intent more clearly than traditional loops.
