Hoisting still occurs within a scope such that, for example, a function defined at the end of a block can be called at the top.
right. The point I was trying to illustrate was that the inner variable declared with a "var" keyword was visible outside its containing block. If I'd used "let" there, it would not be.
e.g.,
function() { var a = 2; // b is visible here if (a == 2) { var b = 3; } }
