Question

I’m pretty sure it cannot be simpler thing to do, hence why I cannot find anything useful about this. Invoking deletion of the element and pushing it so that it becomes last seems too ugly for this.

Five values in an array:

 var array = ['cat', 'dog', 'turtle', 'zebra', 'pterodactylus'];

So, I just want dog to get pushed at the end of the array:

 var array = ['cat', 'turtle', 'zebra', 'pterodactylus', 'dog'];

Simple as that.

Answer 1

function moveToBack( array, index ) {
    array.push( array.splice( index, 1 )[0] );
}
