Let me explain:

* Calculating the array length outside the loop can be slightly faster.
* I pass the item index as the second argument to the called function, since that can often be useful. (The called function doesn’t need to declare it as an explicit argument if it doesn’t need it.)
* If the called function returns anything but undefined, the loop is terminated. This allows us to simulate what would be a break statement in a normal for loop. The ForEach method returns the value returned by the called function.
* If the called function returns undefined, the loop continues. (A function returns undefined if it gets to the end without hitting a return statement, if it hits a return statement without an expression, or if it hits a return undefined (naturally).) An explicit return statement without an expression thus simulates what would be a continue statement in a normal for loop.
* Using the call method allows us to specify this for the called function, which can be useful when calling ForEach from an object method.
* The objThis argument is optional, but I make sure that it is never undefined, because under Internet Explorer, the call method is slightly faster when the first argument is a valid object (passing undefined forces it to determine the “global” object itself).

e.g.
function SumArray(array)
{
  var nSum = 0;
  ForEach(array, function (n) { nSum += n; });
  return nSum;
}
*/
function ForEach(array, fn, objThis)
{
  objThis = objThis || this;
  var len = array.length;
  for (var n = 0; n < len; n++)
  {
    var r = fn.call(objThis, array[n], n);
    if (r !== undefined)
      return r;
  }
}


function FindInArray(array, find)
{
  var index = ForEach(array,
    function (item, n)
    {
      if (item == find)
        return n;
      return null;
    });
  return index === undefined ? -1 : index;
}
