🌟 My solution to exercises from book "Mostly adequate guide to Functional Programming".

Mostly Adequate Exercises

Overview

All exercises from the book can be completed either:

• in browser (using the version of the book published on gitbook.io)
• in your editor & terminal, using npm

In every folder named ch** from this exercises/ folder, you'll find three types of files:

• exercises
• solutions
• validations

Exercises are structured with a statement in comment, followed by an incomplete or incorrect function. For example, exercise_a from ch04 looks like this:

// Refactor to remove all arguments by partially applying the function.

// words :: String -> [String]
const words = str => split(' ', str);

Following the statement, your goal is to refactor the given function words. Once done, your proposal can be verified by running:

npm run ch04

Alternatively, you can also have a peak at the corresponding solution file: in this case solution_a.js.

The files validation_*.js aren't really part of the exercises but are used internally to verify your proposal and, offer hints when adequate. The curious reader may have a look at them :).

Now go and learn some functional programming λ!

About the Appendixes

Important notice: the exercise runner takes care of bringing all data-structures and functions from the appendixes into scope. Therefore, you may assume that any function present in the appendix is just available for you to use! Amazing, isn't it?
