No I can't. I'm just quoting from the books.

I didn't go into the reasons why Crockford advises not using function
statements. They are:
- "the second form makes it clear that [myFunction] is a variable
containing a function value. To use the language well, it is important
to understand that functions are values"
- "function statmenes are subject to 'hoisting'. This means that
regardless of where a function is placed, it is moved to the top of
the scope in which it is defined. ... It also prohibits the use of
function statements in if statements. ... "
It doesn't seem to me that these imply that there will be a different
scope, but I'm not sure.
