title: Does uglify-js support es6 and above?
body: <p>I am watching this video : <a href="https://www.youtube.com/watch?v=kHifDVw5t_w" rel="nofollow noreferrer">https://www.youtube.com/watch?v=kHifDVw5t_w</a> . And in this video it is mentioned that <code>uglify-js</code> does not support es6 and above version of js. But when I try to minify js code(Es6 and above) with the help of <code>uglify-js</code>, it is perfectly minify the js file and did not throw any error.</p>
