    Good Afternoon all,

    I am currently learning JavaScript, My task is to remove items from localStorage.
    The set keys are timestamps for example 
    
// Make a key using a fixed timestamp
    key = "diary" + "1536771000001";.

// Make a key using a fixed timestamp
    key = "diary" + "1536771000002"; (ETC)
    Code (JavaScript):
    However, when i go to remove these items using localStorage.removeItem('diary1536771000002'); every time i click the delete button on any item it removes the diary1536771000002 all the time and not the right key for that text item.

    I am not looking for the direct answer but can someone point me in the right direction?

    I suspect that you have the delete buttons calling the same function but the function has the key hardcoded.

    An alternative might be to have buttons with data-key='diary1536771000002' and then the click event picks up the dataset.key value.
