---

import { jsonpath } from "json-p3";

const data = {
  users: [
    { name: "Sue", score: 100 },
    { name: "John", score: 86 },
    { name: "Sally", score: 84 },
    { name: "Jane", score: 55 },
  ],
};

const nodes = jsonpath.query("$.users[?@.score < 100].name", data);
console.log(nodes.values()); // [ 'John', 'Sally', 'Jane' ]
