Group Array of JavaScript Objects by Key or Property Value
This fork of JamieMason's implementation changes the key parameter to be an array of keys instead of just a single key. This makes it possible to group by multiple properties instead of just one.
const groupBy = keys => array =>
array.reduce((objectsByKeyValue, obj) => {
const value = keys.map(key => obj[key]).join('-');
