Gain the basics of Rubys map, reduce, and select functions and discover how to use them to solve dataprocessing problems. This compact handson book explains how you can encode certain complex programs in 10 lines of Ruby code, an astonishingly small number. You will walk through problems and solutions which are effective because they use map, reduce, and select. As you read Ruby Data Processing, type in the code, run the code, and ponder the results. Tweak the code to test the code and see how the results change.After reading this book, you will have a deeper understanding of how to break dataprocessing problems into processing stages, each of which is understandable, debuggable, and composable, and how to combine the stages to solve your dataprocessing problem. As a result, your Ruby coding will become more efficient and your programs will be more elegant and robust.What You Will Learn Discover Ruby data processing and how to do it using the map, reduce, and select functionsDevelop complex solutions including debugging, randomizing, sorting, grouping, and moreReverse engineer complex dataprocessing solutionsWho This Book Is ForThose who have at least some prior experience programming in Ruby and who have a background and interest in data analysis and processing using Ruby.
