Using underscore.js group the objects using multiple values. By default underscore not support the multiple value groupBy. Here we have to do the trick to achive the functionality.

_.groupBy will group the values using object keys or metric to group the objects or arrays. Let’s write the code. Find the code and example below

Underscore.JS groupBy Multiple values

_.groupByMulti = function (obj, values, context) {     if (!values.length)         return obj;     var byFirst = _.groupBy(obj, values[0], context),         rest = values.slice(1);     for (var prop in byFirst) {         byFirst[prop] = _.groupByMulti(byFirst[prop], rest, context);     }     return byFirst; };
