delete all items in localstorage code example

Example: local storage remove multiple items

//You could just put the keys to remove in an array and loop over them:

let keysToRemove = ["summaryForm", "projectForm"];

for (key of keysToRemove) {
    localStorage.removeItem(key);
}
//Using a full loop, or, using forEach:

keysToRemove.forEach(k =>
    localStorage.removeItem(k))

//Or use localStorage.clear() if you want to just clear everything.
