Angular-cli 8 - Is it possible to build only on es2015? : <p>In version 8 of angular-cli, the build is done 2x. One in es5 and one in es2015.</p>

<p>Is it possible to build only on es2015?</p>

<p>Changing the target to es5, it is done only in es5 .. But I have not found a way to do it only in es2015.</p>
