Ruby/Rails/Sinatra vs. JS/Node/Express

While not strictly a competition (one of the skills you have to practice is knowing which frameworks you should use in which situations), let's compare some differences.

Why Choose Sinatra/Rails?

• Quickest path to building app with full CRUD
• Better at working with complex data relationships - ActiveRecord rocks!
• When full page refreshes aren't an issue
• Synchronous programming is probably a little easier to grasp in building a straightforward program

Why Choose Node/Express?

• JavaScript everywhere, one language to rule them all
• Asynchronous means generally faster performance
• Better concurrency – it can serve data to more users with fewer computer resources
• Designed to make realtime applications
