How do different array methods compare in performance?

The performance of array methods like map, filter, and forEach can vary based on the operation and data size. Would you like a detailed comparison?

Yes, please provide a comparison of map vs forEach.

Generally, map is faster than forEach when you need to transform data because it returns a new array. forEach is better for side effects.

What about filter? How does it compare to map?

Filter is used to create a new array with elements that pass a test. It's typically slower than map because it involves a conditional check for each element.

Can you give me an example of when to use each method?

Sure! Use map when you want to transform data, filter when you need to select specific items, and forEach for executing a function on each item without returning a new array.
