import { from } from "fromfrom";

const users = [
  { id: 1, name: "John", age: 31, score: 2244, active: true },
  { id: 2, name: "Jane", age: 32, score: 2492, active: false },
  { id: 3, name: "Luke", age: 33, score: 2500, active: false },
  …
  { id: 1000, name: "Mary", age: 34, score: 2290, active: true },
];

from(users)
  .filter(user => user.active)
  .pick("id", "name", "score")
  .sortByDescending(user => user.score)
  .take(5)
  .toArray();

// End result:
// [
//   { id: 214, name: "May",   score: 5622 },
//   { id: 353, name: "Peter", score: 5212 },
//   { id: 32,  name: "Macy",  score: 5112 },
//   { id: 972, name: "Laura", score: 5023 },
//   { id: 429, name: "Bob",   score: 4900 }
// ]

I believe your commented result is from a different iteration of the sample code? You're showing more fields in the result than in the pick command in the code.

@Gwunhar There is a shorthand in the users array that suggests 1,000 objects. See the "..." on line 7 and the numbering of ids from 1, 2, 3 to 1,000.

@ganorberg I think he refers to the pick("id", "name", "score) while in the end result there's also age and active

@ganorberg I think it's not about "..." just about method pick(), which takes only three fields but in result we see 5 fields in one object

there's a score. instead of score: on line 8 please fix, it's triggering my OCD :D definitely gonna use this

Thank you for your comments! The previous version was indeed erroneous. The end result objects should only contain properties id, name and score. It should be now fixed
