how to scan javascript code to find errors (are there any programs do that) ?

+2 A:

Load it into Firefox, and use Firebug plugin. It enables you to debug JavaScript, and to see where errors are located in your code.

JSLint will hurt your feelings :)

@Daniel Vassallo: Whereas some browsers will hurt your feelings by passively-aggresively gobbling up error messages and then being deliberately unhelpful. "Object expected on line 0", know what I mean? ;)

A:

Yes, a number of programs have plugins etc that can be used to detect common errors and syntax problems.

If I were you I would start here, JS Lint or here

In addition, each most browsers have a Javascript console where you can see errors reported and debug your code. Safari and Chrome have it in-built, for Firefox download Firebug.
