What are some alternatives to Ruby's filter method?

You can use methods like select, reject, or even map with a condition to filter elements in Ruby.

Can you explain how the select method works?

Sure! The select method returns a new array containing all elements of the original array for which the given block returns true.

How does reject differ from select?

reject is the opposite of select; it returns a new array excluding the elements for which the block returns true.

Are there any performance differences between these methods?

Yes, performance can vary based on the size of the array and the complexity of the block. Generally, select and reject are quite efficient.
