IN THIS CHAPTER
Converting strings into object references
Creating URL-friendly strings
Adding comments to scripts
In addition to all the objects and other language constructs described in the preceding chapters of this reference part of the book, several language items need to be treated on a global scale. These items apply to no particular objects (or any object), and you can use them anywhere in a script. If you read earlier chapters, you were introduced to many of these functions and statements. This chapter serves as a convenient place to highlight these all-important items that are otherwise easily forgotten. At the end of the chapter, note the brief introduction to several objects that are built into the Windows-only versions of Internet Explorer.
Global functions are not tied to the document object model. Instead, they typically enable you to convert data from one type to another type. The list of global statements is short, but a couple of them appear extensively in your scripting.
