When should I use array methods in JavaScript?

Array methods are useful for manipulating and processing arrays efficiently. They can simplify your code.

Can you give me examples of common array methods?

Sure! Common array methods include .map(), .filter(), .reduce(), .forEach(), and .find(). Each serves a different purpose.

How do I decide which method to use?

It depends on your goal: use .map() for transforming data, .filter() for selecting items, and .reduce() for aggregating values.

Are there performance considerations I should keep in mind?

Yes, some methods can be more performance-intensive than others, especially with large arrays. It's good to test and optimize.
