  var wrapper = {

Tests:

chain
console.log( chain(data) // Group the elements of Array based on `color` property .groupBy("color") // `key` is group's name (color), `value` is the array of objects .map((value, key) => ({ color: key, users: value })) .value() );
custom
var custom = (x) => { var group = _.groupBy(x, 'color'); return _.map(_.entries(group), ([ color, val ]) => ({ color, val })) } console.log(custom(data))
