&gt; How useful is it to know about C-style memory management when you&#x27;re a front-end JavaScript Developer?<p>Try making your own particle engine and a simple game running at 60fps. I guess &quot;avoiding GC&quot; is only a very small subset of memory management, but if you&#x27;re a noob like me, it surely will open your eyes about some things you would never have guessed could cause problems.
