A Common-Sense Guide to Data Structures and Algorithms: Level Up Your Core Programming Skills
Algorithms and data structures are much more than abstract concepts. Mastering them enables you to write code that runs faster and more efficiently, which is particularly important for today's web and mobile apps. This book takes a practical approach to data structures and algorithms, with techniques and real-world scenarios that you can use in your daily production code. Graphics and examples make these computer science concepts understandable and relevant.
Use Big O notation, the primary tool for evaluating algorithms, to measure and articulate the efficiency of your code, and modify your algorithm to make it faster. Find out how your choice of arrays, linked lists, and hash tables can dramatically affect the code you write. Use recursion to solve tricky problems and create algorithms that run exponentially faster than the alternatives. Dig into advanced data structures such as binary trees and graphs to help scale specialized applications such as social networks and mapping software. You'll even encounter a single keyword that can give your code a turbo boost. Jay Wengrow brings to this book the key teaching practices he developed as a web development bootcamp founder and educator.
Use these techniques today to make your code faster and more scalable.

In ancient times, meaning the 1960s and 70s, writing code that involved floating-point calculations was like navigating a minefield. Different computers had different ideas about rounding and precision, and when it came to comparing values, they all had quirks that would produce incorrect and downright crazy results at times.
Things are a lot more stable now, because programmers got together and, over the years, developed an IEEE standard for how floating-point math should work.
Normalized and denormalized, zero and negative zero, infinity and negative infinity, Quiet NaN and Signalled NaN, ULPs and biased exponents, it’s all standardized. In this issue, Jim Bonang digs right down to the bit patterns in explicating the intricacies of comparing floating point numbers — and along the way explores the origins of virtual reality, in a meaty article that is both deep and entertaining.
All this year in PragPub Venkat Subramaniam is showing how to refactor your Java code to functional style by taking advantage of functional and declarative features of Java 8. It’s really a great tutorial on how to rethink problems from a functional perspective, regardless of language.
This month he shows how much time and effort can be saved by using the more advanced builtin functions of a language rather than falling back on primitive functions. Avoiding this common anti-pattern, primitive obsession, pays off especially well in functional languages, which pack a lot of power into their higher-level functions.
Most people tasked with hiring programmers would probably agree that asking an interviewee to write a Quicksort on the whiteboard while you watch is dumb. And most would also agree that the ability to understand algorithms is something you want to test for. Is there a better way to do algorithms interviews than the way we’ve been doing it?
Jay Wengrow, author of A Common-Sense Guide to Data Structures and Algorithms: Level Up Your Core Programming Skills, thinks there is, and shares it with us this month.
Frequent contributor Erica Sadun has been tracking the development of the Swift language, and shares some nifty tricks you can do with the latest features in Swift 4.
Regular columnists Johanna Rothman, Marcus Blankenship, Antonio Cangiano, and John Shade are on board as well. It’s a jam-packed issue. We hope you enjoy it!
