Forgive me for the ignorance (I'm a front end dev), but can someone explain to me why this made it to the front page of hacker news when there are already many resources for learning data structures?<p>I feel like I could just go through the docs for for java / kotlin collections lib and cracking the code interview, and get a good understanding of DS / algos. What would this offer beyond that?<p>(this is a genuine question, btw, no sarcasm, there is something here that is resonating with other folks, but not me and I would like to know what that is)
