Data Structures and Algorithms with JavaScript : Michael McMillan: Book

Product descriptions:

As an experienced JavaScript developer moving to server-side programming, you need to implement classic data structures and algorithms associated with conventional object-oriented languages like C# and Java. This practical guide shows you how to work hands-on with a variety of storage mechanisms—including linked lists, stacks, queues, and graphs—within the constraints of the JavaScript environment.

Determine which data structures and algorithms are most appropriate for the problems you’re trying to solve, and understand the tradeoffs when using them in a JavaScript program. An overview of the JavaScript features used throughout the book is also included.

This book covers:

  • Arrays and lists: the most common data structures
  • Stacks and queues: more complex list-like data structures
  • Linked lists: how they overcome the shortcomings of arrays
  • Dictionaries: storing data as key-value pairs
  • Hashing: good for quick insertion and retrieval
  • Sets: useful for storing unique elements that appear only once
  • Binary Trees: storing data in a hierarchical manner
  • Graphs and graph algorithms: ideal for modeling networks
  • Algorithms: including those that help you sort or search data
  • Advanced algorithms: dynamic programming and greedy algorithms

What animal is that on the cover?

The animal on the cover of Data Structures and Algorithms Using JavaScript is an Amur hedgehog (Erinaceus amurensis), also known as the Chinese hedgehog. This species is 1 out of 14 that can be found worldwide today, and is native to Amur Krai and Primorye in Russia, Manchuria in China, and the Korean Peninsula. Like most hedgehogs, the Chinese hedgehog prefers tall grasses and undergrowth. In the wild, they feed on worms, centipedges, insects, mice, snails, frogs, and snakes. Named for the distinct noise made as they forage for food, they hunt primarily using their senses of smell and hearing. Their sniff often resembles a pig-like grunt.

The Amur hedgehog weighs an average of 1.3 to 2.2 pounds and measures between 5.5 to 12 inches in length, its tail measuring around 1-2 of those inches. As a deterrent to predators (such as birds or wild dogs), the hedgehogs are covered in short, smooth spines. If threatened, the hedgehog rolls up into a ball, leaving only the spines exposed; this is also the position in which the hedgehog sleeps, usually in cool dark depressions or holes.

Hedgehogs are solitary animals, not often socializing with other hedgehogs even when encountered while out foraging for food. The only time hedgehogs socialize is during mating season, after which they go their separate ways, leaving the female hedgehog to raise any young that were conceived. Females are very protective of their young; male hedgehogs have been known to eat their young.
