  It is used for local variables. put this in your timeline:
  test =function(){
  var testme="good"
  trace (testme);
  }
  test();
  trace (testme);

  and youll get:
  good
  undefined

  use this
  function test =function(){
  this.testme="good"
  trace (testme);
  }
  test();
  trace (testme)
  then you'll get
  good
  good

  And it would works just the name using:

  function test(){
  var testme="good"
  trace (testme);
  }
  test();
  trace (testme);

  or

  function test(){
  testme="good"
  trace (testme);
  }
  test();
  trace (testme);
