One thing I&#x27;ve been waiting for (and if I had the time, I&#x27;d love to work on something like this) is scientific javascript. I love es6 and classless oop[0] that javascript provides (and general dynamic-ness) but the lack of operator overloading makes mathy infix operators work with an array-like type not possible in native js. Something that had the &quot;functional&quot;, dynamic semantics of javascript with the natural notation that numpy has (with its broadcasting rules) would be fantastic.<p>Stuff like plotly is great, but as far as I can tell, I&#x27;m not going to be able to use it any time soon because I&#x27;m not going to write a &gt;10 term expression in javascript when every &#x27;+&#x27; becomes a &#x27;add(a,b)&#x27; or &#x27;a.add(b)&#x27;.<p>[0] <a href="https:&#x2F;&#x2F;youtu.be&#x2F;bo36MrBfTk4?t=33m45s" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;bo36MrBfTk4?t=33m45s</a>
