JScript

JScript is a scripted programming language from Microsoft , which is an implementation of the ECMAScript standard . JScript syntax is very similar to Netscape's JavaScript , but, in addition to adding client scripts to web pages (which was the only JavaScript function before the Mozilla project appeared), JScript can also be used for other purposes, for example:

• automate the administration of Windows systems;
• creating ASP pages.

Here is an example of a small JScript program that (when launched within the Windows Script Host ) brings up a dialog box (the characters after the signs // are comments ):

  // Declare a variable
  var strMessage ;
  // Assigning a variable to a value
  strMessage = "Wikipedia is the free encyclopedia" ;
  // Display message
  WScript .  Echo ( strMessage );

To run the script from the command line , the following command is usually used (in the case of a file named file.js ):

  cscript file.js
