It feels like the author made the jump straight from PHP to Go without spending much time actually using Node or Ruby and he&#x27;s subsequently shocked at how much better modern languages are when contrasted to PHP.<p>Many of these &quot;solved problems&quot; have also been solved with the other languages, albeit not always at the surface level. For Node specifically:<p>WebSockets -&gt; SockJS, Socket&#x2F;Engine.io<p>Concurrency -&gt; Generator Functions<p>Testing -&gt; import assert from &#x27;assert&#x27; and npm test<p>Syntax -&gt; Some great improvements with ES6 and solid styleguides (airbnb, standard) + eslint as an autoformatter<p>The major win here for Go is that as a new platform it was designed with simplicity in mind. These features are probably easier to pick up in Go than any of the alternatives, which is great. However, don&#x27;t make the mistake of thinking that Go is the first language to solve these problems.
