Discussion on: How to Deep Clone an Array in JavaScript

// Old javascript

function cloneDeeply(arrayToClone) {

  var newArray = [];

  for (var i = 0; i < arrayToClone.length; i++) {

    if (arrayToClone[i].isArray) {
      cloneDeeply(arrayToClone[i])
    }
    else {
      newArray.push(arrayToClone[i])
    }
  }

  return newArray;
}

// Then to use it

var clone = cloneDeeply(yourArrayToCloneGoesHere);
