Javascript was created by both Sun Microsystems and Netscape and was first used in Netscape Navigator. Javascript allows a webmaster to create a range of applications for a web page such as email forms, show the date and time and much more. JavaScript is the "glue" that binds together HTML and XML elements accessed through the browser's Document Object Model (DOM). JavaScript was created by Netscape to be a portable language independent of the underlying operating system as well as a secure language which would protect the user from unwanted system access.
