What are the best array methods for performance in JavaScript?

Some of the best array methods for performance include map, filter, and reduce. They are optimized for functional programming.

Can you explain why these methods are considered performant?

Sure! These methods are often implemented in a way that minimizes overhead and can take advantage of optimizations in the JavaScript engine.

Are there any situations where I should avoid using them?

Yes, if you're working with very large arrays or need to perform operations in a tight loop, traditional for loops might be more efficient.

What about using forEach? Is it efficient?

forEach is generally less performant than map or for loops because it doesn't return a value and has more overhead.
