JavaScript does not really have classes, but yes, you can include
external javascript files:

<script language="JavaScript" src="myexternal.js"></script>

Note that this can only be done in HTML.

Sure. Create your objects with their associated methods and properties, put
them in a .js file and include them on your page with:

<head>
<!-- other stuff -->
<script type="text/javascript" src="MyDictionary.js"></script>
</head>

Then in MyDictionary.js you might have:

function MyDictionary() {
this.RemoveAll();
}
MyDictionary.prototype.RemoveAll = function() {
this.obj = {};
this.Count = 0;
}
MyDictionary.prototype.Add = function(key, value) {
if (this.obj[key] != null) {
return null;
}
this.obj[key] = value;
this.Count++;
return value;
}
MyDictionary.prototype.Exists = function(key) {
return (this.obj[key] != null);
}
// etc

And you could use it in your page like this:

<script type="text/javascript">
var y = new MyDictionary();
y.Add ("a", "test");
if (y.Exists("a")) {
document.write("a exists in MyDictionary");
}
</script>
