Since this code uses ES6 artifacts, any code meant to run on the browser must be transpiled with either:

• Babel
• Traceur

For Node.js users. This code requires:

node --version > 6.3.1

Please begin the project with

$ npm install

to load all of the required functional libraries.

In this repo you will find:

• All code samples (as runnable unit tests) of code used in chapters
• JS targeted for browser
• Functional data types like Optional, Either, Maybe, etc.
• Access to some JavaScript functional libraries like lodash.js, rxjs, etc.

Once QUnit is installed, you can run each test with the QUnit CLI by specifying the chapter number.

$ npm run ch[01-08]

Additionally, you may also run unit tests using the Jest test runner. Disclaimer: This is not part of the book, but an extra feature courtesy of the JS community :-)

To run all tests:

$ npm test

To run a chapter test:

$ jest ch[01-08]

To run tests in watch mode:

$ jest --watchAll

And for code coverage:

$ npm run cover
