Summary

In this chapter, we worked with transforming and filtering operators to model our Observable sequences. The chapter was majorly divided into two sections; in the first section, we learned how to transform the outputs from one Observable sequence to match the inputs as expected by other subscriptions, and in the second section, we learned how to select the elements from an array of elements that suit our requirements. We saw how we can chain a number of operators to perform a consolidated action and noted how this process improves the readability of code. You might have felt the difference while working with the declarative style of programming, since operators perform a major chunk of work under the hood without dishing out the implementation details. Moving on, we will get into how we can combine multiple Observables into a single Observable sequence. You will work with operator chaining to even more detailed levels. There's nothing to worry since we will follow the same stepwise approach of adding operators and explanations at each step while chaining the code so that you understand the code at each and every step. Finally, congratulations on making it so far! We are nearly halfway through. Kudos!
