javascript - does this variable get hoisted no matter what? -

What is the code inside the false block, even if var foo is hoisted on top of the stack Can not be executed at any time?

  function foo () {if (false) {var foo = 'bar'; // Will it never be executed, even if it is hoisted? }}   
 I see that this is and it's just confused ... I did not expect that it would be wrapped in false cases.   
 
 
 Yes; The code is hosting before the code runs, so  if  statement comes out or not  true  or  false  is not yet known.
