JavaScript: can I somehow strong type function parameters?

I am a newbie with JavaScript and I feel the unresistible need to strong type my functions parameters for a couple of tools I am coding:

That would give me autocompletion within those functions

Debugging/function access gets more consistent

After some googling, I guess this isn't directly possible. However, are there common tools to emulate this rather simply?

What are your thoughts?

No, you can't and even if there is a way you shouldn't. JavaScript is a dynamically typed language. For auto completion you can however use JSDoc style documentation tags that give some type pointers:

var Person = {

    /**

     * Say hi

     * @param {String} name The name to say hi to

     * @return {String}

     */

    sayHi : function(name)

    {

        return 'Hi ' + name;

    }

}

If they are being used depends entirely on your IDE though.
