π Overview - Unit 6
The purpose of this unit is to extend the robust theoretical model established in Unit 5 to more dynamic and complex real-world scenarios. Here, you will master four practical primitives built on top of the core APIs of Unit 5 to elegantly solve advanced problems.
- Handling Absence (
n
prefix API): How to safely and declaratively handle the possibility that real-world data may benull
within the Timeline structure, without relying on anOption
type. - Chaining Asynchronous Operations (
bind
chain): Building on the foundation of nullability, how to compose potentially failing asynchronous operations into a single, safe, sequential process by chainingbind
. - Temporal Evolution of State (
scan
): A method for evolving βstateβ along the timeline by accepting new inputs based on past states. - Noise Reduction (
distinctUntilChanged
): A technique to optimize performance by capturing only essential changes and suppressing unnecessary updates.
These are a powerful set of tools that specialize the capabilities of the core APIs for specific application areas and are essential for building robust applications.
