-```sh
-
-// the "true" argument must be removed if used

 **ES Check** checks JavaScript files against a specified version of ECMAScript (ES) with a shell command. If a specified file's ES version doesn't match the ES version argument passed in the ES Check command, ES Check will throw an error and log the files that didn't match the check.
