Manufacturers Association (ECMA). It was standardized under the name ECMAScript and it is vendor-neutral standard. Visual Basic Script (VBScript) on the other hand is a Microsoft supported language. When a person is surfing the web, they click on a link which will cause the browser to make a request for a specific HTML page or other type of file from a web server (HTTP server). These servers contain pages that are sent to the client using the HTTP protocol normally serviced on port 80. The HTML page may contain JavaScript which is run by the browser when the HTML page or other type of file is loaded.

Tutorialized.com Javascript, which does not need to be compiled, adds functionality to web pages. It can be made to perform a number of useful tasks, such as respond to user actions, validate data, and more. If you want to make your web site more interactive, the tutorials in this section will show you how.

Wowarea.com Javascript is a script language developed by Netscape Communication Corporation. It isn't a programming language like the Java language. Javascript's statements are embedded in an HTML page (you should know the HTML language before following this course...). When you download a web page by means of a client such as Netscape Navigator or Internet Explorer, the client reads the page from top to bottom, displaying it according to HTML rules. However you can also use Javascript. Javascript scripts are freeware, because you can read HTML pages in order to discover how they are built. I could say that Javascript is a 'cut&pasteware' language...In fact, all you need is inside of the HTML page (a piece of that page): just cut and paste it! Netscape Navigator's versions previous to 2.0 can't interpret Javascript, so if you have those versions, I suggest you a newer version (while I'm writing, the current Netscape's browser version is the 4.0). I think it is worth, because by means of Javascript you can do fantastic things. In addition, the current Javascript version is the 1.2 (in this case you need Netscape Navigator 4.0, because Navigator 3.0 can't interpret Javascript version higher than 1.1). Javascript is an object oriented script language and its statements are quite similar to C language statements. If you know Java or Visual Basic or C++ you can understand me when I talk about 'Object Oriented Programming Language' and about 'Events'. However, if you don't know these languages, don't worry: Javascript is really simple, and I will explain you all these concepts.
