A design study on function composability
What is a Design Study?
I use the term "design study" for a specific type of deliberate practice in which I take one or more design ideas and explore them as much as possible.
What is function composability?
One of the core ideas in functional programming is to create mathematical-style functions.
This creates a few interesting design blocks:
- small functions with a general application domain
- functions that bind one argument to a value and return another function (also called currying, or partial application)
- a function resulted from the composition of two or more functions (as in j(x) = f(g(h(x))) )
- functions that transform a function into another function (meta!)
What is this design study about?
This design study uses a simple find operation with multiple criteria to explore the world of currying and composition.
Do you plan to work more on it?
Maybe, I don't know. I might find it interesting to revisit, or to go into more details.
What can I do with it?
I mainly did this for myself, and decided to share it with the world as an experiment.
So read the code, and I hope you'll learn something. Even better, try to do it yourself (fork might work well for this).
Oh, and let me know if you have ideas about other design studies.
