to_array.rb

This Ruby code snippet demonstrates reading a file line by line, removing trailing whitespace (like newlines) from each line, and returning an array of strings where each string represents a line from the file. File.readlines reads the file, and .map(&:chomp) iterates through each line, applying the chomp method to remove the newline character.

Ruby code snippet

File.readlines('input/file/file.txt').map(&:chomp)
#=> ["line1", "line2", "line3"]
