    Variables in JavaScript are implicitly global, so unless they are within a function and prefixed with the var keyword, they will be globally accessible

    This is global

    <script type='text/javascript'>
    foobar = 'hello';
</script>

    This is also global

    <script type='text/javascript'>
   function test() {
       foobar = 'hi';
   }
</script>

    This is local

    function test() {
    var foobar = 'world'; 
}
