## Example

```javascript
import { jsonpath } from "json-p3";

const expr = "$.users[?@.status == 'pending'].name";

const data = {
  users: [
    { id: "usr_101", name: "Alice", status: "pending" },
    { id: "usr_102", name: "Bob", status: "active" },
    { id: "usr_103", name: "Charlie", status: "pending" },
  ],
};

const nodes = jsonpath.find(expr, data);

console.log(nodes.map((n) => n.value)); // [ "Alice", "Charlie" ]
console.log(nodes.map((n) => n.location)); // [ [ "users", 0, "name" ], [ "users", 2, "name" ] ]
console.log(nodes.map((n) => n.normalizedPath())); // [ "$['users'][0]['name']", "$['users'][2]['name']" ]
console.log(nodes.map((n) => n.shorthandPath())); // [ "$.users[0].name", "$.users[2].name" ]
console.log(nodes.map((n) => n.pointer.toString())); // [ "/users/0/name", "/users/2/name" ]
```
