I have an array like this

arr = [orange,red,black,white]

I want to augment the array object defining a deleteElem() method which acts like this:

arr2 = arr.deleteElem(red); // [orange,black,white] (with no hole)

What is the best way to accomplish this task using just the value parameter (no index)?

Here's how it's done:

var arr = [orange,red,black,white];

var index = arr.indexOf(red);

if (index >= 0) {

  arr.splice( index, 1 );

}

This code will remove 1 occurency of red in your Array.
