Javascript: var myFunc = function() vs. var myFunc = function myFunc()

Question

What is the difference between these?

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

vs.

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

In the 2nd example, arguments.callee.caller.name works, but not in the first one. Is there anything wrong with the 2nd syntax?

Answer 1

The second one has a name while the first one doesn't. Functions are objects that have a property name. If the function is anonymous then it has no name.

var a = function(){}; // anonymous function expression
a.name; //= empty

var a = function foo(){}; // named function expression
a.name; //= foo
