There’s a reason my copy of “JavaScript: The Good Parts” is extremely slim next to its sibling, “JavaScript: The Definitive Guide”.&lt;p&gt;So you’ve come to it at a time when the syntax and capabilities have a popular subset that actually starts to fulfil the early promise. And yet, despite the article above, one may still be enormously critical of the anemic and inconsistent standard library, and don’t even get me started on the horrifying dependency shitshow of the node ecosystem that cripples maintainability of anything over 18 months old.&lt;p&gt;Just because we’re all holed up in the throne room, doesn’t mean there aren’t monsters still roaming the sewers, just a few levels down.&lt;p&gt;As for isomorphic code, I strongly encourage my competitors to write backend code in the same fashion and the same breath as the front-end, because the resulting tight coupling and special-case-driven technical debt makes them easy to outmanoeuvre when markets shift. And if they’re reading this then please also consider microservices, graphql,
and nosql data stores whilst you’re at it, for the same great reasons.</text><parent_chain><item><author>hn_throwaway_99</author><text>Couldn&amp;#x27;t disagree more.

<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>sillyquiet</author><text>I agree with this - EXCEPT:&lt;p&gt;In a backend where you need a heavy-duty, multithreaded process to handle long-lived computations, node is &lt;i&gt;probably&lt;/i&gt; not the way to go unless you want to pay for all the extra instances you&amp;#x27;d need for the same amount of load.  In my experience, for example, a java-based graphQL server (that spawned multiple connections to various services) needed much much less in the way of resources than the node equivalent serving the same amount of traffic  - AND the latencies were generally much better with the java server, depending on the size of the JSON payloads that it was handling.&lt;p&gt;All that being said, you can certainly architect your way out of that problem and I imagine a relatively small percentages of web applications even HAVE that problem.</text><parent_chain><item><author>hn_throwaway_99</author><text>Couldn&amp;#x27;t disagree more.
