The Essentials of Writing High Quality JavaScript | Nettuts+

The brilliant Stoyan Stefanov, in promotion of his new book from O’Reilly, “JavaScript Patterns,” was kind enough to contribute an excerpt of the book for our readers, which details the essentials of writing high quality JavaScript, such as avoiding globals, using single var declarations, pre-caching length in loops, following coding conventions, and more.

This excerpt also includes some habits not necessarily related to the code itself, but more about the overall code creation process, including writing API documentation, conducting peer reviews, and running JSLint. These habits and best practices can help you write better, more understandable, and maintainable code—code to be proud of (and be able to figure out) when revisiting it months and years down the road.
