Things I learned at NDC London: Reactive Extensions Training Camp

After the first 2 days of workshops, NDC London continued with lots of great speakers and sessions. I was planning to share some information during the conference itself but due to technical difficulties I had to postpone it. For the next few days I will be sharing some of the great content.

Rx (Reactive Extensions)I’m a big fan of reactive extensions although I still have a hard time to grab my head around it. During one of the Rx sessions I heard that Netflix contributed a great series of interactive exercises for learning Microsoft's Reactive Extensions (Rx) Library for JavaScript as well as some fundamentals for functional programming techniques:

This is a series of interactive exercises for learning Microsoft's Reactive Extensions (Rx) Library for Javascript. So why is the title "Functional Programming in Javascript"? Well it turns out that the key to learning Rx is training yourself to use functional programming to manipulate collections. Functional programming provides developers with the tools to abstract common collection operations into reusable, composable building blocks. You'll be surprised to learn that most of the operations you perform on collections can be accomplished with five simple functions:

  1. map
  2. filter
  3. mergeAll
  4. reduce
  5. zip
