More directly, Javascript is lexically/statically scoped (the scope is
where the function is declared, not where it is called). So, you can
safely use functions within your script's namespace. A simple example:
function doSomething() {
  alert( "two" );
}
someElement.addEventListener( "click", function(){ alert( "one" );
doSomething(); }, false );
