Eloquent JavaScript

Marijn Haverbeke 'spricht' mit Begeisterung zahlreiche unterschiedliche Programmiersprachen. Sein Weg führte von trivialen BASIC-Spielen auf dem Commodore über die C++-Phase in die Gegenwart, in der er sich vor allem mit Datanbank-Systemen und WEB-APIs von dynamischen Sprachen beschäftigt. Er entwickelte und unterhält eine Reihe von bekannten Open-Source-Projekten.

JavaScript is at the heart of almost every modern Web application, whether it's Google Apps, Twitter or the newest browser-based game. Though it's simple for beginners to pick up and play with, JavaScript is not a toy - it's a flexible and complex language that can be used to build full-scale applications.

Eloquent JavaScript dives into this flourishing language and teaches you to write code that's beautiful and effective. By imersing you in example code and encouraging experimentation right from the start, the author quickly gives you the tools you need to build your own programs. As you follow along with examples like an artificial life simulation and a version of the classic game Sokoban, you'll learn to:

- Understand the essential elements of programming: syntax, control, and data

- Use object-oriented and functional programming techniques to organize and clarify your programs

- Script the browser and make basic Web applications

- Work with tools like regular expressions and XMLHttpRequest objects

And since programming is an art that's best learned by doing, all example code is available online in an interactive sandbox for you to experiment with. With Eloquent JavaScript as your guide, you can tweak, expand, and modify the author's code, or throw it away and build your own creations from scratch. Before you know it, you'll be fluent in the language of the Web.

A beginner's guide to programming in JavaScript that focuses on writing real applications, rather than on using JavaScript to create simple browser effects.- JavaScript is a must-learn web programming language
- Beginner-friendly, accessible approach
- Focuses on clean, elegant programming practices, and avoids the "ugly" parts of JavaScript
