The Web languages and interfaces researched represent various attempts to create the "ideal" Web programming language, usually by extending and restricting existing languages. They have a variety of ancestors: scripting languages, shell languages, mark-up languages and conventional programming languages. Web programming languages shows their ancestry in their syntax, computational and data model, and implementation style, and as a result, there are a fair number of distinct approaches taken. Also known as Interpreted Languages, they have become more and more popular. In recent years, interpreted language such as Java, VB Script and Perl are the hot topics and wide-spread. Generally, it is because they are portable, easy to use, fast to develop and safe. And most interpreted languages are closely related to Web programming. In this paper, we will compare and contrast some of the Web programming languages and do some study to expose the nature of interpreted programming languages and how these features of interpreted languages are achieved.
