Test ascending Javascript array of Date objects

Question

I have a javascript array of Date objects, which I'd like to test for ascendingness. This is what I built, but I am kind of disappointed by it. Any suggestion?

function isAscending(timeLine) {
  if (timeLine.length < 2)
    return true;

  for(var i=1; i < timeLine.length; i++) {
    if(timeLine[i-1] > timeLine[i])
      return false;
  }
  return true;   
}

(I was hoping for something more expressive, built-in, some library math function etc.)

Answer 1

That's the simplest way to do it; don't be disappointed.

Answer 2

How about

function isAscending(timeLine){
    var i=0, L= timeLine.length-1;
    while(i<L){
     if(timeLine[i]> timeLine[++i]) return false;
    }
    return true;
}
