To run the program, first ensure you have node installed. Then git clone the repo to your local filesystem and npm install.
Also ensure you have jasmine-node installed globally: npm install -g jasmine-node.
Add a file to the root folder called config.js and export your Google Maps API Key:
module.exports = { GOOGLE: <<your API key here>> }
The program may then be run through the terminal with node distanceBetweenCities.js.
Tests may be run through the terminal via jasmine-node cities.spec.js --verbose.
To add or change the cities to be included, edit cities.txt.
