In computer programming, a script is a program or
sequence of instructions that is interpreted or carried out by another
program rather than by the computer processor (as a compiled program is).
Some languages have been conceived expressly as script languages. Among
the most popular are Perl, Rexx (on IBM mainframes), JavaScript, and Tcl/Tk.
In the context of the World Wide Web, Perl, VBScript, and similar script
languages are often written to handle forms input or other services for
a Web site and are processed on the Web server. A JavaScript script in
a Web page runs "client-side" on the Web browser.
In general, script languages are easier and faster to code in than the
more structured and compiled languages such as C and C++. However, a script
takes longer to run than a compiled program since each instruction is
being handled by another program first (requiring additional instructions)
rather than directly by the basic instruction processor.
