Description: 

The internal yarn build:js and yarn watch:js commands are deprecated in Drupal 9.4.0. Drupal Core will no longer include a build step in Drupal 10.0.0 since all of the browsers supported by Drupal Core are compatible with ES6. Since the build tool is no longer needed by Drupal Core, there isn't any replacement for it.
