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;
};
