Учусь несколько месяцев результата нет..

setInterval(ajax, 5000);

function ajax(){
   //AJAX
}

Подскажите куда копать?

const data = [
  { name: 'Sasha', apple: 8, banana: 6, cherry: 9 },
  { name: 'Artur', apple: 4, banana: 2, cherry: 1 },
  { name: 'Sasha', apple: 5, banana: 7, cherry: 3 },
  { name: 'Bogdan', apple: 6, banana: 11, cherry: 8 },
  { name: 'Artur', apple: 8, banana: 6, cherry: 9 },
];

const collectBy = (collection, property) =>
  collection.reduce((accumulator, entry) => {
    const { [property]: key, ...data } = entry;

    if (!accumulator.hasOwnProperty(key)) {
      accumulator[key] = data;
    } else {
      for (const [property, value] of Object.entries(data)) {
        accumulator[key][property] += value;
      }
    }

    return accumulator;
  }, {});

const collectedData = collectBy(data, 'name');

console.log(collectedData);
/*
{
  Sasha: { apple: 13, banana: 13, cherry: 12 },
  Artur: { apple: 12, banana: 8, cherry: 10 },
  Bogdan: { apple: 6, banana: 11, cherry: 8 }
}
