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

If order the array (changing positions) won't be a problem you can solve like:

var arr = ["orange","red","black","white"];
arr.remove = function ( item ) {
  delete arr[item];
  arr.sort();
  arr.pop();
  console.log(arr);
}

arr.remove('red');
