An example of an AI chatbot conversation about using filter and reduce methods in Ruby.
How do I use filter and reduce in Ruby?
In Ruby, you can use the select method to filter elements and reduce to accumulate values. Would you like an example?
Yes, please provide an example of both.
Sure! For filtering, you can use array.select { |num| num.even? } to get even numbers. For reducing, array.reduce(0) { |sum, num| sum + num } sums up the elements.
Can you explain how reduce works in more detail?
Absolutely! The reduce method takes an initial value and a block. It iterates through the array, applying the block to accumulate a single result.
