Most of the time, these scripts include step-bystep instructions that explain where to put the functions, what elements to use in your page, and how to hook your elements up to functions using events.
However, there’s a downside to free JavaScript. As you learned at the beginning of this chapter, JavaScript dates back to the early days of the Internet, and many Java-Script sites are nearly as old.
