/**
 * The Loader class for autoloading of Highcharts modules. This class is part of
 * the `highcharts-autoload.js` bundle, and is used for dynamically loading
 * Highcharts modules on demand based on the chart configuration options.
 *
 * The Loader analyzes the chart options for features that require additional
 * modules. The Loader will load the required modules asynchronously before
 * instantiating the chart.
 *
 * For styled mode and Stock Tools, the Loader also adds the required CSS files.
 * An exception is when using ESM modules, where you need to define the CSS in
 * link tags.
 *
 * No extra configuration is required to use the Loader, the static class
 * methods below are for advanced use cases.
 *
 * @example
 * const chart = await Highcharts.chart({
 *     chart: {
 *         type: 'arearange'
 *     },
 *     series: [[0, 2], [4, 3]]
 * }, true) ;
 *
 * @sample highcharts/global/autoload-esm ESM setup with bubble chart and
 *         modules
 * @sample highcharts/global/autoload UMD setup with stock chart and modules
 *
 * @class
 * @name Highcharts.Loader
