JavaScript Regular Expressions

This is a great book on quickly getting started with writing quality regular expressions in JavaScript. More importantly, it helps you to understand the syntax and pattern development of regular expressions.

This is written in a clear and concise manner-even a newbie, with only a basic knowledge of the JavaScript language, can easily use it. Each section builds on the previous sections. I think the book is well worth while for any JavaScript programmer.

I got a lot of Regex knowledge from this book

"JavaScript Regular Expressions" provides what its title suggests: an introduction to using regular expressions in JavaScript. This relatively short book (fewer than 100 substantive pages) features five chapters along with an appendix. The appendix provides several useful tables that demonstrate regular expressions concepts and patterns, descriptions of those concepts and patterns, and example code that illustrates those concepts and patterns."JavaScript Regular Expressions" provides a nice introduction to regular expressions in general and to specifically applying regular expressions in JavaScript code. There are numerous simple examples that are accompanied by explanatory text. I especially liked an example of a simple HTML page that could be used to test simple regular expressions and I liked that this example was introduced early and then that tool was used for a couple more chapters' examples. I also liked the clear examples of how to create common web form validation regexp patterns.The electronic version (PDF) I reviewed has color screen snapshots for its illustrations. Code listings are black text on white background with no line numbers and no color syntax. Code can be downloaded to be viewed in one's favorite IDE or text editor.Much of the coverage of regular expressions in "JavaScript Regular Expressions" would be of benefit to developers using regular expressions in any language. However, there are parts of the book that are specific to using regular expressions in JavaScript and this book is obviously best suited to JavaScript developers, especially given that there are numerous general and comprehensive regular expressions books available.There are a few sentence structures in "JavaScript Regular Expressions" that I had to read more than once to clearly understand what the authors were stating. There is reference in the Preface to online color screen snapshots that are supposed to accompany this book (presumably for readers of printed copies), but it appears to me that the PDF that the link points to is for an unrelated Packt book.Packt Publishing provided me with the PDF version of "JavaScript Regular Expressions" that I reviewed, but I did not receive any compensation for this review.

IMHO, every developer should learn and know about regular expressions. While they might seem hard for some to grasp initally, the gained benefit can be huge. Whether it's to simplify your code (especially when it comes to text parsing) or simply to do some advanced search&replace within your favorite text editor (i.e. Sublime, Atom etc....). If you don't know regex yet, you have not the minimal idea of how much they can make you more productive in such situations.JavaScript Regular Expressions approaches the field of regular expressions from the JavaScript side. The book starts out slowly, giving the reader a short, but concise intro to the regular expression syntax before then diving into practical examples - which is my favorite part. The strong relation to practical scenarios is what makes the book interesting and not just purely theoretical (which is a big risk when talking about regex in general).So as mentioned, you won't regret getting this book, especially if you want to become a seasoned JavaScript developer :)

This workbook describes how to use javascript regular expressions in your code.There are several case studies for parsing and validating web forms, and a full example of analysing an apache log file using node.js. The appendix acts as a reference and covers the standard in seven tables.However, it does not cover some advenced topics like handling character encoding by using special libraries (http://xregexp.com/), or unit testing the regular expressions (like unitjs.com).

Eine Aktualisierung des Buches notwendig. Leider nicht mehr aktuell, daher Beispiele bedingt richtig.
