Anonymous and Named Function Expressions

var clickHandler = function() {
  // ...
};

var keykHandler = function keykHandler() {
  // ...
};

The first function is called anonymous function expression
The second function is called named function expression

You should always use named function expression and there are three reasons for that:

1. Handy function self-reference (e.g. recursion)
2. More debuggable stack traces
3. More self-documenting code
