Hey, that's actually a valid point. JSLint is entirely constructed on opinion, and it not the word of god.

However, general good practice is to declare all your variables in one place, at the start of the function block they are in:

function doSomething() {
    var a, b, c, d;
    a = 1;
    c = 10;
    for( b = a; b < c; b++) {
        d = b*2 + a-c;
        alert(d);
    }
}
