delete 1 item from local storage array

Question

I have a local storage item as per below

(2) [{…}, {…}]
0
:
cityName
:
"durban"
__proto__
:
Object
1
:
cityName
:
"cape town"
__proto__
:
Object

I would like to delete 1 item only, based on whether the cityName matches the local storage item i.e if the user clicks "durban" then delete durban.

I already am able to get the name from the click

  deleteCity(event){
    var target = event.currentTarget.id;
    console.log(target);
    var getLSCityName = localStorage.getItem('savedLocations');
    var getLSCityNameArr = JSON.parse(getLSCityName);

      for(var i = 0; i < getLSCityNameArr.length; i++){
        if (getLSCityNameArr[i].cityName == target){
          getLSCityNameArr.splice[i].cityName;
          localStorage.setItem('savedLocations', JSON.stringify(getLSCityNameArr));
        }
      } 
    }

after you "do something here", you'll need to, a) JSON.stringify it, then b) write it back to localStorage - if the savedLocations represents an array, then use array filter method to remove the desired item — Jaromanda X

please try like this

function deleteItem(index){
            var getLSCityName = localStorage.getItem('savedLocations');
            getLSCityName.splice(index,1); // delete item at index
        }

ok this works

deleteCity(event){     var target = event.currentTarget.id;     var getLSCityName = localStorage.getItem('savedLocations');     var getLSCityNameArr = JSON.parse(getLSCityName);        for(var i = 0; i < getLSCityNameArr.length; i++){         if (getLSCityNameArr[i].cityName == target){           getLSCityNameArr.splice(i, 1);           localStorage.setItem('savedLocations', JSON.stringify(getLSCityNameArr));         }       }    }
