how to map an array with uppercase function in javascript?

Question

I\'m interested if there is any function like array_map or array_walk from php.

Don\'t need an for that travels all the array. I can do that for myself.

Answer 1

Similar to a previous for loop answer, this one uses some of the more basic features of javascript:

function looptoUpper(arr){
    var newArr = [];
    for (var i = 0; i < arr.length; i++){
        newArr.push(arr[i].toUpperCase());
    }
    return newArr;
}
looptoUpper(['dom', 'lun', 'mar', 'mer', 'gio', 'ven', 'sab']);
