Alternative "is it new" for the old function node block for N8N

fonctions.js

const new_items = [];
const data = this.getWorkflowStaticData('node');

data.ids = data.ids || [];

for (var i=0; i<items.length; i++) {
  if (data.ids.includes(items[i].json.id)) {
    break;
  } else {
    new_items.push({json: {id: items[i].json.id, url: items[i].json.url, name: items[i].json.name}});
  }
}

data.ids = items.map(item => item.json.id)
return new_items;
