Javascript - named function declaration or assign to a variable?

in javascript

What's the difference between assigning an anonymous javascript function to a variable or just declaring a named function in the first place? Turns out "hoisting" of the function only works if you declare it as a named function in the first place. Assigning an anonymous function to a variable doesn't perform the hoist.

<html>
  <body>
    <script>

      (function() {
        console.log(f()); // 'hello'
        function f(){
          return 'hello';
        };
      })();

      (function() {
        console.log(f()); // undefined
        var f = function() {
          return 'hello';
        };
      })();

    </script>
