This is an advanced functional programming topic, but I want to summarize only a couple of important points
- Map and Reduce
If you know C# very well, you should have learnt that Linq is good way to introduce functional programming techniques and F#. For example compare reduce with aggregate… and start to familiarize with the accumulator value pair.
The elegance of the transducer pattern is that transformers compose naturally to produce new transformers. So we can chain as many transformers together as we like, and since we end up with one transformed reducer, we only iterate over the collection once. We don’t need to create intermediate copies of the data or iterate over it multiple times.
