This talk demonstrates with examples how to write better Ruby code using some lesser known, underused ruby/rails methods & abstractions. Don’t miss this talk if you want to learn about some simple yet powerful methods like ‘enum#flat_map’ & ‘object#tap’ that can help you code like a pro using Ruby
I couldn’t help but notice how cool
Object#tap is to get rid of the temporary variables in my code and
Array#bsearch is 3 times faster than
find when working on large arrays. So I started looking for other cool methods like those and found quite a few of them. But sadly, whenever I talk about these methods, most of my fellow devs don’t even know they exist!
This talk discusses these methods( around 25 to 30 ) with example snippets that are classified into the following major groups.
- Ruby Enumerable
- Ruby Date Time
- Number and string formatting
- Rails specific
- Active Record
Apart from discussing lesser known useful methods, this talk also tries to demonstrate the lesser known use cases of popular methods like
. For example, passing a block to
count like this
numbers = [1,2,3,4,5]
I have been writing Ruby code for the past 2 and half years for a living. This talk is inspired by what I learned from my efforts to write clean, maintainable ruby code and I hope this talk will help my fellow developers to ship better code and to stop reinventing the wheel all over again
