&gt; As a user, my experience with HTML&#x2F;CSS&#x2F;JS apps is great. Look at the excellent feedback the Atom Editor is getting.<p>For some less positive feedback on Atom, which reinforces some of creshal&#x27;s points, see the Atom section of this text editor rundown:<p><a href="http:&#x2F;&#x2F;eev.ee&#x2F;blog&#x2F;2015&#x2F;05&#x2F;31&#x2F;text-editor-rundown&#x2F;" rel="nofollow">http:&#x2F;&#x2F;eev.ee&#x2F;blog&#x2F;2015&#x2F;05&#x2F;31&#x2F;text-editor-rundown&#x2F;</a><p>I&#x27;ve also frequently seen complaints to the effect that Atom is much too slow, even on machines only a few years old. Even my 486 laptop back in 1997 could run a text editor with syntax highlighting (specifically, JPad for programming in Java). What are editors doing these days that needs so much CPU power?
