Also about exercise 2, extra credit 3... The solution has this:

function asyncReducer(state, action) {
  switch (action.type) {
    case 'pending': {
      return {status: 'pending', data: null, error: null}
    }
    case 'resolved': {
      return {status: 'resolved', data: action.data, error: null}

// Get data
let newToDelete = [];
for (const element of document.querySelectorAll(".mn-connection-card")) {
    newToDelete.push([element.querySelector("a").href, element.querySelector(".mn-connection-card__name").textContent.trim(), element.querySelector(".mn-connection-card__occupation").textContent.trim()])
}

// Copy data to clipboard
copy(JSON.stringify(newToDelete));
