All software design is composition: the act of breaking complex problems down into smaller problems and composing those solutions. Most developers have a limited understanding of compositional techniques. It's time for that to change.
In "Composing Software", Eric Elliott shares the fundamentals of composition, including both function composition and object composition, and explores them in the context of JavaScript. The book covers the foundations of both functional programming and object oriented programming to help the reader better understand how to build and structure complex applications using simple building blocks.
You'll learn:
- Functional programming.
- Object composition.
- How to work with composite data structures.
- Closures.
- Higher order functions.
- Functors (e.g., array.map).
- Monads (e.g., promises).
- Transducers.
- Lenses.
