Whether you need an example-driven programmer's guide or
a complete desk reference, JavaScript: The Definitive
Guide is the most authoritative book on this language
that runs the Web. The sixth edition offers comprehensive
coverage of ECMAScript 5 (the new language standard) and
also the new APIs introduced in HTML5. The chapters on
functions and classes have been completely rewritten and
updated to match current best practices. There is a new
chapter that covers language extensions and subsets.
