Standalone JavaScript programs

[Hussein Baghdadi]

Hi,
I'm not a JavaScript Ninja so my question may sound really silly.
Is there a way to run JavaScript code outside the browser. I'm looking for something like:
terminal $ jsvm binary-tree.js
Thanks all.

Another solution is using JRE6 Scripting API (javax.script.*). This is suitable if the JS code does not involve changing its container - for example, you can't use this to reliably run JS code that manipulates browser DOM.
It's good for testing data structures, or following DRY principles (example: parameter validation rules can be coded just once in JS and invoked from both client side and server side).

Example:

...
	public static void main(String[] args) {
		ScriptEngineManager scrMgr = new ScriptEngineManager();
		List<ScriptEngineFactory> factories = scrMgr.getEngineFactories();
		if (factories != null) {
			for (ScriptEngineFactory fac : factories) {
				System.out.println(fac.getEngineName() + " - " + fac.getLanguageName());
			}
		}
		
		ScriptEngine jsEngine = scrMgr.getEngineByName("JavaScript");
		try {
			jsEngine.eval(new FileReader("test.js"));
			Invocable caller = (Invocable)jsEngine;
			caller.invokeFunction("test", "myargument");
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (ScriptException e) {
			e.printStackTrace();
		} catch (NoSuchMethodException e) {
			e.printStackTrace();
		}
	}
