The term "hoisting" can mislead someone who doesn't know that it refers
only to the variable and function declarations, not to the variable
assignment. For example, the code below:
f();
function f() { alert(x); }
var x = 42;
is implicitly executed as:
var x;
function f() { alert(x); }
f();
x = 42;
This behaviour is according to the specification:

Imprecise terminology.
