/**
 * Hook to retrieve the user's current location.
 *
 * The hook returns an array of three elements:
 *
 * 1. The current location as an object with latitude and longitude
 *    properties. The initial value is `{ latitude: 0, longitude: 0 }`.
 * 2. An error string if an error occurred while retrieving the location,
 *    or `null` if no error occurred. The initial value is `null`.
 * 3. A function to request the user's location permission and retrieve
 *    the current position. The function takes no arguments and returns
 *    no value.
 *
 * The hook uses the `getCurrentPosition` method of the `Geolocation`
 * API to retrieve the user's location. The request is made with high
 * accuracy mode enabled.
 *
 * @returns An array with the current location, an error string (or null),
 *          and a function to request the user's location permission.
