Do you prefer?

var foo = true;
if (some condition){
var foo = false;
}

Or

if (some condition){
var foo = false;
}
else{
var foo = true;
}

undefined

    first is way more intuitive.. "have this, but update it if condition matches" readability wins

    First every time, the else block is just useless confusion

    Second one doesn't work in languages like Java, because of scope reasons.

    I prefer -

    var foo = some_condition;

    Keep it simple. :-)

    var foo = (some condition) ? 'bar' : 'blah';

    The first. Why are you redeclaring foo though? You already said "var foo" but then you do it again in the conditional block. Wouldn't it just be "foo" in there?

    Is this a trick question. Obviously, make sure it exists first, and assume the worst.
