lenght

function

in

Array

// public method
 deleteItem(position = this.state.selectedItem) {
  const { items } = this.state;
  // if focus on ae_end and last action is a text, remove text
  if (position === -2 && items[items.length - 1].type === "text") {
   // recursive call on last item position
   this.deleteItem(items.lenght - 1);
   return;
  }
  // console.log("delete item ", deletePosition);
  if (position > -1 && position < items.length) {
   items.splice(position, 1);
   this.updateItemsAndContent(items);
   const itemToFocus = position > 0 ? position - 1 : position; // move focus to previous item
   this.changeFocus(itemToFocus);
  }
 }

// Express validator
app.use(expressValidator({
