AQA 7517 4.12.2.1: Functional language programs
The free BugBot lessons that teach this point, a robot to try it on, and the past-paper questions that test it.
Lessons that teach it
- A13.1 The functional paradigm Functional programming
Side effects, pure functions and referential transparency, immutability and statelessness, with the robot's side effects kept at the edges. - A13.3 First-class objects and higher-order functions Functional programming
Functions as values in variables, lists and dictionaries, passed as arguments and returned as results, lambdas, closures and a robot… - A13.5 Map, filter and fold Functional programming
The three higher-order functions, foldl and foldr, and a pipeline over a log of sensor readings. - A13.8 Project: the way out Functional programming
Sweep the bay, decide with a pipeline of pure functions built by composition, map, filter and fold, then drive out.
