Question:

How to avoid variable overlap problems (stepping on the fellow engineers' toes)

Answer:

Use namespaces as shown below. Make all functions members of an object - here named pt_scope - that is instantiated exactly one time. Then call functions as members of this global object.

<script language=javascript>
function go() {

var pt_scope = {
	a: function() {alert('hello'); },
	b: function() {document.write('junk'); }
  }


  pt_scope.a();
  pt_scope.b();
}
</script>
<a href=javascript:go()>GO</a>
