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

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?

lewdogg9958yIs this a trick question. Obviously, make sure it exists first, and assume the worst.
Do you prefer?
var foo = true;
if (some condition){
var foo = false;
}
Or
if (some condition){
var foo = false;
}
else{
var foo = true;
}
undefined
