Hello Dev.to,
Today, I want to introduce a fantastic Computer Science resource to all of you - A book, that was a good kickstart when I was an absolute beginner and a handbook as I started advancing.
I know that a book may not always be everybody's favorite, but hey, the author has added some super nerdy cartoon comic strips and he has ensured that the monotony is as minimal as possible (it's a book; The monotony just can't be helped ;))
This book deals with the Complexities (Time & Space), Strategies, Data Types, Structures, Programming Paradigms etc - Just a perfect guide!
So without further delay, this is the book -
And a small sneek peak into the contents:

Enough dopamine? I'd highly recommend you all to get this book (I'm in no way related to the author and this is not an advertisement :); It's just that it's really hard to find a 168-page book that concisely explains all of the important pillars of Computer Science and this is my favorite book of all time! :) That said, I just want to ensure that I pass this on to all of you, so that atleast one of you may be benefitted.
