I was a self taught software engineer that later went to grad school to get a masters in software engineering. What I learned along the way was that many of the intimidating subjects around algorithms and data structures were much simpler and less scary than I ever thought.

My hope for this book is to try and help the self taught developers get on more equal footing with people who have a CS degree - at least the algorithms class - which I always thought was most important for interviews. Along the road, I realized Big O, logs, and algorithmic complexity weren't as confusing as I first thought. This book hopes to close the gap between self taught developers and formal CS knowledge - which often gave me imposter syndrome.

The linked PDF is a complete chapter from the book about common data structures you'll encounter in javascript - and leaving out some of the data structures you may never see (like Linked Lists).

Note - this is one chapter of the book that was published and is available on Amazon. There's a link on the last page of the PDF to the book's website and the Amazon link.
