Now that we have the means for creating
Observable instances from a wide variety of source data, it's time to build programming logic around these instances. We will present the basic reactive operators that we'll use to achieve step-by-step computations (the reactive way of handling data).
We will begin with transformations, using the famous
map() operators, as well as some more less common transforming operators. After that we'll learn how to filter our data, using the
filter() operator, skipping elements, receiving only elements at a given position in time. The chapter will also cover accumulating data with the
scan operator. Most of these operators will be presented ...
