JavaScript
From Simple English Wikipedia, the free encyclopedia
JavaScript is a programming language for a computer. Very often, it is run in a web browser application that allows the use of dynamic content like message boxes popping up or a live clock. Some people call it a scripting language. It is different from the Java programming language.
The following sample script causes a message box to appear in the web browser. Type this into the address bar.
javascript:window.alert("Message")
