Remove a value from Javascript, leaving it as undefined (null)

Encountering an issue when attempting to remove an element fetched from my API call, as the deleted element is leaving behind an "undefined" value.

var nutrientsLink = "http://api.nal.usda.gov/ndb/list?format=json&lt=n&sort=n&api_key=JXUX86YZ9mBl4jwofXb3GcwQcYehmUxQ23JwjK1q&offset=58&max=1000";

    //Requesting data from nutrientList URL
    $http.get(nutrientsLink).success(function (data) {
         //Removes the specified item from the list
         delete data.list.item[0];
         data = JSON.parse(JSON.stringify(data));
    }
    

Answer №1

If you need to remove the first element of an array, you can use the array.shift method.

data.list.shift()

Answer №2

Make sure to utilize data.list.item.splice(0,1) in place of delete data.list.item[0].
