filter_map vs select, filter, and map methods in Ruby on Rails
Ruby, as an elegant programming language, offers developers a rich collection of tools to work with arrays and hashes, making data transformation and filtering operations a breeze. Among these tools is the filter_map method, introduced in Ruby 2.7, which quickly gained popularity for its simplicity and effectiveness in combining filtering and mapping in a single step. If you’re a Ruby developer or just curious about optimizing your code, understanding filter_map is essential.
