20. name for Function expression

The code will output:

function
function
function
undefined
function
string

When typeof a, typeof b, and typeof c are logged, they will return "function" because a, b, and c are all defined as functions.

When typeof d is logged, it will return "undefined" because d is defined only within the function c using function expression syntax. It is not accessible outside of that function. Therefore, d is not defined in the global scope and is undefined.

When c() is called, typeof d will output "function" because d is still in scope inside of the c function. However, when d is assigned the value of 'e', typeof d will now output "string" because d has been redefined as a string value.
