find largest numerical value in foreach Javascript?`

Question

Ok take the following: fiddle

how do i run a for each collecting the highest value for each of the north values and the lowest for the south in javascript?

Ok i went for this:

    function finder(cmp, arr, attr) {
       var val = arr[0][attr];
       for (var i = 1; i < arr.length; i++) {
           val = cmp(val, arr[i][attr]);
       }
       return val;
   }

Give it a shot! PS: do you realize that what you're trying to do is not a reliable way to get the bounding box? — zerkms

from that answer I'm guessing there isn't a defacto way to do it! — vimes1984

There are nice ways of doing that with, say, Math.min/Math.max — zerkms

Please note that you only have Strings, you should parse the numbers out of them too — Paul S.

Angular has a lovely built in forEach function:

var lowestFound = false;
var lowest = 0;

angular.forEach(values, function(value, key) {
  if (value < lowest || lowestFound === false) {
    lowest = value;
    lowestFound = true;
  }
});

return lowest;

Not perfect, but it should work. :)

You could also add similar code for the highest values in the same function (saving looping over everything twice). :)
