Firstly, delete is a reserved keyword in Javascript.
If you want to remove a single a single record from an array, you would use a splice function on the array.
function myDelete(pointsIndex){
currentData = theData;
newData = currentData.points.splice(pointsIndex, 1);
}
The second parameter in the splice method determines how many items to delete, first is the index from where to start deletion.
