How do maps and filters compare in performance?

Maps and filters are both used for transforming data, but they have different performance characteristics. Maps apply a function to each element and return a new array, while filters return a new array containing only elements that pass a test.

Which one is faster, map or filter?

Generally, map is faster than filter because it processes each element without needing to check a condition. However, the actual performance can depend on the specific use case and the size of the data.

Are there scenarios where filter is more efficient?

Yes, if you only need a subset of the data, using filter can be more efficient as it reduces the amount of data processed in subsequent operations.

Can I chain map and filter together?

Absolutely! You can chain them together, for example, using filter to narrow down the data first and then map to transform the filtered results.
