JAVASCRIPT THE GOOD PARTS - DOUGLAS CROCKFORD K...

Most programming languages contain good and bad parts  but JavaScript has more than its share
of the bad  having been developed and released in a hurry before it could be refined. This
authoritative book scrapes away these bad features to reveal a subset of JavaScript that's more
reliable  readable  and maintainable than the language as a whole—a subset you can use to
create truly extensible and efficient code. Considered the JavaScript expert by many people in
the development community  author Douglas Crockford identifies the abundance of good ideas that
make JavaScript an outstanding object-oriented programming language-ideas such as functions 
loose typing  dynamic objects  and an expressive object literal notation. Unfortunately  these
good ideas are mixed in with bad and downright awful ideas  like a programming model based on
global variables. When Java applets failed  JavaScript became the language of the Web by
default  making its popularity almost completely independent of its qualities as a programming
language. In JavaScript: The Good Parts  Crockford finally digs through the steaming pile of
good intentions and blunders to give you a detailed look at all the genuinely elegant parts of
JavaScript  including: * Syntax * Objects * Functions * Inheritance * Arrays * Regular
expressions * Methods * Style * Beautiful features The real beauty? As you move ahead with the
subset of JavaScript that this book presents  you'll also sidestep the need to unlearn all the
bad parts. Of course  if you want to find out more about the bad parts and how to use them
badly  simply consult any other JavaScript book. With JavaScript: The Good Parts  you'll
discover a beautiful  elegant  lightweight and highly expressive language that lets you create
effective code  whether you're managing object libraries or just trying to get Ajax to run
fast. If you develop sites or applications for the Web  this book is an absolute must.
