/**
 * A `LngLat` object represents a given longitude and latitude coordinate, measured in degrees.
 * These coordinates use longitude, latitude coordinate order (as opposed to latitude, longitude)
 * to match the [GeoJSON specification](https://datatracker.ietf.org/doc/html/rfc7946#section-4),
 * which is equivalent to the OGC:CRS84 coordinate reference system.
 *
 * Note that any method that accepts a `LngLat` object as an argument or option
 * can also accept an `Array` of two numbers and will perform an implicit conversion.
 * This flexible type is documented as {@link LngLatLike}.
 *
 * @class LngLat
 * @param lng - Longitude, measured in degrees.
 * @param lat - Latitude, measured in degrees.
 * @example
 * ```typescript
 * const ll = new LngLat(-123.9749, 40.7736);
 * console.log(ll.lng); // = -123.9749
 * ```
