EN

const data = [
  {
    libele: 'AAA',
    Fonds: 'xxx',
    Estimation: '122',
    Parts: '11',
  },
  {
    libele: 'AAA',
    Fonds: 'yyy',
    Estimation: '111',
    Parts: '12',
  },
  {
    libele: 'BBB',
    Fonds: 'zzz',
    Estimation: '111',
    Parts: '12',
  },
  {
    libele: 'BBB',
    Fonds: 'aaa',
    Estimation: '111',
    Parts: '12',
  },
  {
    libele: 'CCC',
    Fonds: 'aaa',
    Estimation: '111',
    Parts: '12',
  },
];

const grouped = data.reduce((total, item) => {
  const existingGroup = total.find((group) => group.libele === item.libele);

  if (existingGroup) {
    existingGroup.data.push(item);
  } else {
    total.push({
      libele: item.libele,
      data: [item],
    });
  }

  return total;
}, []);

console.log(grouped);
