In Douglas Crockford's "JavaScript: The Good Parts", Crockford names global variables as the worst part of JavaScript. He writes, "Global variables can be a convenience in very small programs, but they quickly become unwieldy as programs get larger. Because a global variable can be changed by any part of the program at any time, they can significantly complicate the behavior of the program. Use of global variables degrades the reliability of the programs that use them."
