How is it really advanced?<p>I was under the impression that it&#x27;s just another dynamic scripting language semantically equivalent to Perl5, Python, Ruby, JavaScript, and so on.<p>And obviously new languages of this kind aren&#x27;t going to be very successful or interesting because knowing and using JavaScript is going to be mandatory forever due to  browsers and with Babel and ES6&#x2F;7 it&#x27;s as good as any other such language.<p>Plus in addition to JavaScript, Ruby, Python and PHP have a lot of momentum as well.
