Table 1-2 shows the core language version and DOM capabilities supported by various browser versions from Netscape and Microsoft. Note that the versions of Internet Explorer listed in the table refer to the Windows version of that browser. The capabilities of Macintosh versions of IE often vary (sometimes significantly) from the same-numbered versions for Windows. Also, bear in mind that IE allows the JScript interpreter to be upgraded independently of the browser itself, so it is possible to encounter an installation of IE that supports a version of the language greater than that shown here.
