Chris@0:  * Provides the build:js command to compile *.es6.js files to ES5.
Chris@0:  *
Chris@0:  * Run build:js with --file to only parse a specific file. Using the --check
Chris@0:  * flag build:js can be run to check if files are compiled correctly.
Chris@0:  * @example <caption>Only process misc/drupal.es6.js and misc/drupal.init.es6.js</caption
Chris@0:  * yarn run build:js -- --file misc/drupal.es6.js --file misc/drupal.init.es6.js
Chris@0:  * @example <caption>Check if all files have been compiled correctly</caption
Chris@0:  * yarn run build:js -- --check

Chris@0:  * @internal This file is part of the core javascript build process and is only
