About this Book
There's an art to writing third-party JavaScript—embeddable scripts that can
plug into any website. They must adapt easily to unknown host environments,
coexist with other applications, and manage the tricky security
vulnerabilities you get when code and asset files are served from remote web
addresses. Get it right and you have unlimited options for distributing your
apps. This unique book shows you how.
