Confusion of function scopes in various browsers

Source: Internet
Author: User
If (true) {function somefunc () {return 1 ;};} else {function somefunc () {return 2 ;}}var notsomefunc = function somefunc () {return 3 ;}; alert (somefunc ());

FF output 1, represented by the existence of "Block scope ".

IE6-IE8 outputs 3, which is a bug that occurs when it handles the namefunction expression, creating two completely different function objects.

The correct output should be 2.
