Answer 1

The first form is actually a variable with an anonymous function assigned to it, the second is a declared function.

They’re almost interchangeable, but have some differences: debuggers have a harder time with anons (because they lack a name) and the JS engine can directly access declared functions wherever they exist in the script, but anons can’t be accessed until they have been assigned.
