Why does the array still have a non-zero length after deletion?

Question

I have the following code that outputs the length of an array, deletes it, and then outputs the new length:

console.log($scope.adviceList.activeAdvices.lengt         


        

Answer 1

I created a new array and pushed elements on it to get the right length. For example, I had this for table headers:

 var finalTableHeaderArray = [];

 tableHeaderArray.forEach(function (element, index, array) {
    if (removeDisplayItems.indexOf(index) === -1)
        finalTableHeaderArray.push(element);
 }, self);

Not exactly your question, but it could help others.
