/**
 * @file
 *
 * Provides the build:js command to compile *.es6.js files to ES5.
 *
 * Run build:js with --file to only parse a specific file. Using the --check
 * flag build:js can be run to check if files are compiled correctly.
 * @example <caption>Only process misc/drupal.es6.js and misc/drupal.init.es6.js</caption
 * yarn run build:js -- --file misc/drupal.es6.js --file misc/drupal.init.es6.js
 * @example <caption>Check if all files have been compiled correctly</caption
 * yarn run build:js -- --check
 *
 * @internal This file is part of the core javascript build process and is only
 * meant to be used in that context.
