Whatever is provided client side is provided by the browser. Most browsers (but not all) provide a JavaScript implementation (and Java). Some browsers offer other languages, but for general use web pages the presence of other languages can't be relied on.

You can easily find pages that require specific language or technology support and which do not render correctly if that support is not available. Often those pages will require a specific browser to ensure the required support is available. It is possible to use Perl client side for example, but it's not commonly done because very few client systems are set up to provide it.

Server side you can use whatever language you can convince your administrator to install so there are effectively no constraints on what can be used.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
