The best way to remove array element by value

Question

I have an array like this

arr = [\"orange\",\"red\",\"black\",\"white\"]

I want to augment the array object defining a deleteElem()<

Answer 1

The best way is to use splice and rebuild new array, because after splice, the length of array does't change.

Check out my answer:

function remove_array_value(array, value) {
    var index = array.indexOf(value);
    if (index >= 0) {
        array.splice(index, 1);
        reindex_array(array);
    }
}
function reindex_array(array) {
   var result = [];
    for (var key in array) {
        result.push(array[key]);
    }
    return result;
}

example:

var example_arr = ['apple', 'banana', 'lemon'];   // length = 3
remove_array_value(example_arr, 'banana');

banana is deleted and array length = 2
