JS Calculator

A lightweight javascript library for parsing calculations as an example for the revealing module pattern and testing with Jasmine.

Usage

In a browser using CDN:

<script src="https://unpkg.com/@perreh/[email protected]/dist/calc.bundle.js"></script>

<script>
    calc(3).add(5); //returns 8
</script>

Using npm:

npm -i --save @perreh/js-calculator

In Node.js

var calc = require('@perreh/js-calculator');

calc(3).add(5); //returns 8

Building

Take a copy of the code if you want to make changes or build the bundle yourself. eslint is used in the build to test code against a style guide.

git clone https://github.com/perryjsteward/js-calculator.git
cd js-calculator
npm install
npm build

build will bundle the file into /dist

Testing

Test the package using Jasmine against original index.js:

npm run test

To test a specific spec file (-- -- is not a typo):

npm test -- --filter="Calculator Minus"
