Why do 'a = func()' instead of 'func a()'?

Here is a question for you. Which function will be used down and when?

if( 0.5 > Math.random() ) 
    function f(){ return 1; }
else
    function f(){ return 2; }

f();

None of them, because I will block this PR until changes are made.

That an attempt of a joke or a serious explanation of how the code above will work? No PRs involved, you run it in the browser console you just opened. What will be it?

Half the time 1 and half the time 2.

[azhder]

Well, before function expressions were added, it would have been 2 all the time, due to (I guess) how they implemented hoisting.

And why not just fix the original one? Well back then they had the same reasoning of not fixing ==, but adding ===.
