Streaming is one of the pillars of writing highly performant Node.js code. It allows us to not block the main thread, while still being able to process data. The Streaming API allows us to write different types of streams for our purposes. While most of these streams will be in the form of transform streams, it is nice to see how we could implement the other three.
The final topic we will look at in the next chapter is data formats. Handling different data formats besides JSON will allow us to interface with many big data providers and be able to handle the data formats that they like to use. We will see how they utilize streaming to implement all of their format specifications.
