Learning JavaScript Data Structures and Algorithms

Chapter 2. Arrays

An array is the simplest memory data structure. For this reason, all programming languages have a built-in array data type. JavaScript also supports arrays natively, even though its first version was released without array support. In this chapter, we will dive into the array data structure and its capabilities.

An array stores a sequence of values that are all of the same data type. Although JavaScript allows us to create arrays with values from different data types, we will follow the best practices and consider that we cannot do that (most languages do not have this capability).

References for JavaScript array methods

Arrays in JavaScript are modified objects, meaning that every array that we create has a few methods available to be used. JavaScript arrays are very interesting because they are very powerful and have more capabilities available than the primitive arrays of other languages. This means that we do not need to write basic capabilities ourselves, such as adding and removing elements in/from the middle of the data structure.

The following is a list of the core available methods in an array object. We have covered some methods already.

Method	Description
`concat`	Joins multiple arrays and returns a copy of the joined arrays
`every`	Calls a function for every element of the array until `false` is returned
`filter`	Creates an array with each element that evaluates to `true` in the function provided
`forEach`	Executes a specific function on each element of the array
`join`	Joins all the array elements into a string
`indexOf`	Searches the array for...

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

This book is one of my favorite algorithm texts. It gets straight to the point providing you with examples of how the data structure or algorithm can be used and application of the algorithm in JavaScript. If you are studying algorithms in school, you're probably using the Cormen text or possibly Sedgewick's or Kleinberg's. Definitely recommend using this as a supplement for those texts.If you're not taking an algorithm class and want to see how to implement common data structures and algorithms in JavaScript, or you're looking to brush-up for a job interview, or you have some JavaScript background and want to improve your skills, definitely pick this up! The price is great as well.

Josh Goldberg Dec 02, 2014

The book's title undersells it a little. The first chapter is a solid, concise introduction to using the language, and is followed by a series of chapters that each bring the reader into a better understanding of how to use both JavaScript and programming concepts in general. I see this book as a good companion for teaching Computer Science II level material in JavaScript. The examples are straightforward and logical, as are the explanations. It's hard to find fault with the book's approach to teaching because there's so little chaff to complain about. It simply teaches you what you need to know, which I found very refreshing.Overall, while the book isn't positioned as the be-all and end-all of understanding the JavaScript language, it is an overall excellent introduction to the language and implementing data structures in it.

I gave this 5 stars in spite of the considerable errata. The author does an excellent job of explaining the fundamentals of data structures and algorithms. If you're going to get a degree in CS, go ahead and pass on this book, but if like me, you discovered your love of computers too late in life, this is your ticket to penetrating some of the mystery surrounding terms like linked lists, hashes, binary trees and their traversals, queues, stacks, graphs, search algos, and sorting. I really wish there were more books like this. You can leave your math books on the shelf, the explanations and programs in this book are conceptual and explanatory. Lots of fun code to type in an play with -- of course you can just download all the code and copy paste, but there's a lot to be said for slowing down and typing it in -- as Donald Knuth said, "Information sinks into the brain at about the same rate it always has," or words to that effect. Some of the programs will make your head hurt. The author, Loiane Groner, can teach... not every writer can.
