groupByOrderByLoadash.md

Use chain to apply groupBy() & orderBy() together with Loadash.

let data = [
  {"name":"foo","id":1},
  {"name":"bar","id":2},
  {"name":"foo","id":2},
  {"name":"foo","id":3},
  {"name":"bar","id":1},
  {"name":"bar","id":4},
];

_.chain(data)
  .orderBy(data => Number(data.id), ["desc"])
  .groupBy(data => data.name)
  .value();
