remove empty spaces from array using angular

Question

im taking first steps in angular, and i need to return array excluding empty spaces in it. i was able to create function to return the array i want, spliced, but couldn't find a way to make sure each cell in the array contains a value. this is my function:

$scope.letters = function(arr) {
    var lettersarray = arr.split('');
    return lettersarray;
};

is there a way to do it in angular?

i know a way in jquery but understood its not recommended to mix both so im looking for an "angularish" way to do it..thx

There's no real "Angular" way to do it, why not just use native JS and .map

function trimArraySpaces(arr) {
    return arr.map(function(item) {
        return item.trim();
    });
}

var testArr = ["John    ", "Sally    "],
    trimmedArr = trimArraySpaces(testArr); //["John", "Sally"]
