Functional Programming
Builds programs from function composition, immutable values, and explicit data transformation
Why learn Functional Programming?
It supports local reasoning and limits hidden state changes
The problem it solves
It manages complexity by treating computation as value-producing expressions
Where it came from
Functional Programming is a programming language and runtime concept that builds programs from function composition, immutable values, and explicit data transformation. Its guarantees and tradeoffs depend on the concrete implementation and operating context.
