πŸ” 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.

  1. Handling Absence (n prefix API): How to safely and declaratively handle the possibility that real-world data may be null within the Timeline structure, without relying on an Option type.
  2. 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 chaining bind.
  3. Temporal Evolution of State (scan): A method for evolving β€œstate” along the timeline by accepting new inputs based on past states.
  4. 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.
