Avoiding Single Operators
Explore how chaining multiple RxJS operators in Angular improves code clarity and flexibility. Understand why using operators like pluck is better than a single complex operator, enabling easy swapping and better readability in reactive programming.

In the last lesson, we used two operators: one for retrieving the value from the input and another for parsing it as an integer. If we wanted to, we could have put everything into a single operator, as shown here:

However, this is not recommended because we won’t be able to swap operators if we ever need to. If we do, we’ll have to change the entire chain. Let’s look at an example.
The pluck operator
