copied!<blockquote> <p>Can I create javascript shell scripts?</p> </blockquote> <p>You bet!</p> <ul> <li>On Windows, you can do this by using <code>cscript.exe</code> (you can even set up a file extension -- I use <code>jx</code> -- that automatically runs when you just double-click the filename or use it as a command in a shell: Just associate that file extension with the command <code>"c:\WINDOWS\system32\cscript.exe" /e:JavaScript /nologo "%1" %*</code>). This is (and I've measured carefully) about 80 milion times better than fighting with Windows' batch language. About. (And if you don't want to use JScript — Microsoft's variant of JavaScript — you even have options, see below.)</li> <li>On *nix, a shell script can be set to run in any installed interpreter (that's what the <code>#!...</code> line at the top is telling the command interpreter). I expect you'll find a few if you search around.</li> <li>On the Mac, you probably have <a href="http://en.wikipedia.org/wiki/WebKit#JavaScriptCore" rel="nofollow noreferrer">JavaScriptCore</a> installed in <code>/System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc</code></li> <li>And on all of the above, if you like, you can install <a href="http://www.mozilla.org/rhino/" rel="nofollow noreferrer">Rhino</a> and Java and get platform independence and access to a huge range of library functionality. Rhino has a built-in shell, or you can tell it to execute a specific JavaScript file. It interoperates with Java, so if you do this, you have <em>easy</em> access to all essentially of the functionality available to Java.</li> </ul> <blockquote> <p>Where is javascript commonly used beside the web browsers?</p> </blockquote> <p>I use it for shell scripting on Windows. I also use it as a server-side language, for instance in the server-side part of a web application. It's also used in other environments where a lightweight, powerful scripting language is useful, such as in the <a href="http://www.mongodb.org/display/DOCS/Home" rel="nofollow noreferrer">MongoDB</a> shell environment (you can use it to query MongoDB data) and stored procedures.</p> <p>All of that said, writing a browser-based project is a rich, interactive way to learn the language.</p>
